Well my rad/rad corrupter is now up to lvl 24 and i'm loving it so far.
the basic attacks aren't the most damaging but recharge quickly and use low end, couple that with a couple of secondary effects in some attacks (knockback from electron haze and disorient from cosmic blaze) as well as all attacks having a def debuff and your on a winner.
the secondaries give you some nice options, acc debuff, res debuffs, slows and choking cloud. although the secondaries tend to drain end.
to me so far it seems very good for pve and my limited experience with pvp looks good as well. toggle drops from disorient to take down tankers, radiation infection on a controller stops him spamming holds, all in all very fun 
I used this post from the US Boards for reference - Its for a rad/rad Defender, but the descriptions of powers are really useful
I think you'll agree this guide rocks -
DodgerTA's Rad/Rad 2.1: A (revised) Twink's Guide
This version of this guide fixes a couple of errors from the recent guide and takes into account the recent changes in Choking Cloud and Phase Shift. It adds some supplementary information and tactics. Also, all Brawl Indexes have been updated to match the scale used by the Brawl Index Database and all numbers included are BASE UNENHANCED numbers.
I am including stats here not only for Rad/Rad but all the Ancillary Power Pools for Defenders as well. All info was obtained through empirical tests on the test server, and is accurate in so far as I've been able to reasonably determine. So here goes:
___________________________________
PART I - RADIATION EMISSION
___________________________________
The powers in the radiation emission primary are diverse and powerful. There are a few disadvantages, but all in all it is probably the most versatile of the defender sets.
___________________________________
Radiant Aura
A solid AoE heal, RA heals for ~13.2% of your HP in a 20-25ft AoE centered around the caster. Even if you don't want to be known as a healer, I recommend you take, and slot, this power. It will help you personally a lot in later levels.
Endurance Cost: 19
Base Heal at 50: 133.86
Duration: Instantaneous
Recharge Timer:8s
Activation Time: 3s
Heal Index: 13.16 % of current HP max without accolades
Recommended Slotting: 3 or more Heal, 1 EndRdx
___________________________________
Radiation Infection
The single most important power in the radiation line. Provides a 33.3% base debuff to enemy accuracy and defense. NOTE: With this build, slot ToHit Debuffs rather than Defense Debuffs. You WILL NOT NEED to enhance its defense debuff.
Endurance Cost: .66 Endo/sec
Base Effect: 33.3% Acc and Def debuff
Duration: Toggle
Recharge Timer:10s
Activation Time: 4s
Recommended Slotting: 5 ToHit Debuff, 1 EndRdx
___________________________________
Accelerate Metabolism
The single most eclectic buff in the game, this is a must-have gem. It provides: a 30% increase to endo recovery, a 30% reduction in recharge times, a 50% reduction in status duration (status effects on you last 1/2 as long), and a 25% damage buff as well as increasing Run and Flight speed. Four recharge slots and perma hasten will make this permanently available. Three recharge slots will give a short downtime but allow additional endo recovery.
Endurance Cost: 24
Duration: 2m
Recharge Modifier: .3
Base Endo Rech: .501 endo/sec
Recharge Timer: 8m, 35s
Activation Time: 2s
Recommended Slotting: 4 Rchg, 2 EndRec or 3 Rchg, 3 EndRec
___________________________________
Enervating Field
This is the '2' in your 1-2 debuff combo. Enervating field provides a ~35% base debuff to enemy damage and a 42% base debuff to enemy damage resistance. Interestingly enough, this damage reduction works out to the same amount of resist Tough will give you, only since it's damage debuff and not resist, will work against all damage types. The resistance debuff increases your own damage output (and that of anybody hitting any of the affected targets) increasing your total damage output by 37.5%, even if your damage is already 'capped'.
Endurance Cost: 1.48 Endo/sec
Base Damage Reduction at 50: 34.3%
Base Damage Increase at 50: 37.5%
Duration: Toggle
Recharge Timer: 10s
Activation Time: 1s
Recommended Slotting: 3-6 EndRdx
___________________________________
Mutation
An excellent combat resurrection, Mutation raises the target hero with full HP and Endo and provides the following benefits for one minute: A 1.0 recharge reduction (cutting any power not slotted for recharge's timer in half), a 100% increase in endo recovery, and a 50% increase in damage, as well as a large accuracy buff.
Endurance Cost: 56.5
Damage Buff: +50%
Recharge Buff Modifier: 1.0
Duration: 1m
Recharge Timer: 3m
Activation Time: 3s
Recommended Slotting: 1 Rech
___________________________________
Lingering Radiation
This buff provides a base 50% reduction in enemy movement speed and attack rate. Slow enhancers can be slotted, but only modify the movement speed debuff. With hasten, this can be stacked to bring enemies down to the attack rate minimum cap (25% base attack rate) and movement debuff cap (10% base movement speed).
Endurance Cost: 23
Duration: 30s
Recharge Timer: 25s
Activation Time: 2s
Recommended Slotting: 2 Slow, 1 EndRdx
___________________________________
Choking Cloud
This power has a 50% chance to hold any enemy in its area of effect for five seconds. Every five seconds it rolls a new to-hit roll on every enemy. Hold Duration enhancements will allow most mobs to be perma-held with this power, although there will always be enemies missed occasionally.
Endurance Cost: 6 every 5 seconds
Base Hold at 50: 5 seconds
Duration: Toggle
Recharge Timer: 90s
Activation Time: 2s
Recommended Slotting: 4 Hold, 1 EndRdx
___________________________________
Fallout
This power uses a friend's corpse as a bomb with a small radius of effect. The animation looks much like Mutation. The damage is excellent and is available once every five minutes. Best use I've found for this power is situational: if a tanker (usually one with perma-unstoppable) is herding, and dies from taking too much damage at the end of Unstoppable's cycle (or just for pulling more than he could chew), you're left with an awful lot of [censored] off mobs right around him. Target him with Fallout and most of them will die. This does damage comparable to an alpha-strike power (nova, atomic blast, etc) but can ONLY be targeted on a fallen teammate.
Endurance Cost: 25
Base Damage at 50: 222
Duration: Instantaneous
Recharge Timer: 5m
Activation Time: 4s
Brawl Index: 17.0667
Recommended Slotting: Not recommended, however, anything less than 1 Acc 5 Dam is a waste IF you decide you want this power.
___________________________________
EM Pulse
A very solid, HUGE AoE hold. This power holds most mobs it its for a base of 45s. It is a magnitude 2 hold (will hold Lt's) and has a 50% chance of adding another magnitude 1 hold (for Mag 3, allowing it to hold bosses). Using it turns off your endo recovery for a while, so be careful with it.
Endurance Cost: 30
Base Damage at 50: 47.41
Duration: 45s
Recharge Timer: 5m
Activation Time: 2s
Brawl Index: 3.6448
Recommended Slotting: 3 Rech, 3 Hold or 2-4 Rech
___________________________________
___________________________________
PART II - RADIATION BLAST
___________________________________
The Radiation Blast secondary is likewise one of the most versatile for Defenders. It has excellent capacity for single-target AND AoE damage, as well as a built-in defense debuff and (in most powers) an innate accuracy bonus. I personally do not slot accuracy because I never need it, and we'll see why in a moment. Defense debuff numbers are best-guess since accuracy is so hard to measure adequately.
___________________________________
Neutrino Bolt
A very fast, low damage power, a bolt from the hand. Its DPS is fairly impressive alone because of the quick recharge, but even with its quick casting time, it will lower the DPS in an attack chain more than any other attack. It has a built-in 10% defense debuff which lasts five seconds.
Endurance Cost: 4
Base Damage at 50: 21.68
Duration: Instantaneous
Recharge Timer: 4s
Activation Time: 1s
Brawl Index: 1.6667
Recommended Slotting: 1 Acc
___________________________________
X-Ray Beam
Lasers from the eyes! A decent damage power that can and will help you in the low levels. It has a good range as well as an innate accuracy bonus (+10% - 85% base acc) and a built-in 10% defense debuff which lasts for 5 seconds.
Endurance Cost: 6
Base Damage at 50: 36.14
Duration: Instantaneous
Recharge Timer: 4s
Activation Time: 1.7s
Brawl Index: 2.7778
Recommended Slotting: 6 Dam
___________________________________
Irradiate
The bread-and-butter of the AoE build, Irradiate is a small self-centered explosion of radiation which does approximately X-Ray Beam damage in a Point Blank AoE radius (About 20 feet), and couples it with a 10% innate accuracy bonus (85% base acc) and a 30% defense debuff which lasts 15 seconds. With Radiation Infection and Irradiate, enemy defense is lowered so much you'll rarely miss even unslotted for accuracy. A very fast activation time (~1s) makes this power even better.
Endurance Cost: 22
Base Damage at 50: 3.6 * 10
Duration: 5s
Recharge Timer: 20s
Activation Time: 1s
Brawl Index: .2778 * 10
Recommended Slotting: 4 Dam, 1 Rech, 1 EndRdx
___________________________________
Electron Haze
A billowing green cloud that deals very decent damage, EH is a cone attack with knockback. The knockback is unreliable (5-10% chance). It does better damage than your other 2 AoE attacks, but is slow to activate (2.5-3 seconds of animation lock) making its cone nature harder to use. It carries a 10% innate accuracy bonus and a 10% defense debuff which lasts for five seconds.
Endurance Cost: 18
Base Damage at 50: 48.79
Duration: Instantaneous
Recharge Timer: 16s
Activation Time: 3s
Brawl Index: 3.7500
Recommended Slotting: 5 Dam, 1 EndRdx
___________________________________
Proton Volley
The niftiest sound in CoH. This power fires four large green balls of radiation toward your target for superior damage. It has a 20% base accuracy bonus and a built in 10% defense debuff which lasts for 5 seconds. Slotted with 1 interrupt reducer, the interrupt time is ~1 second, after which you can move around freely and the attack will still go off as long as you have a Line of Sight to your target when it completes.
Endurance Cost: 17
Base Damage at 50: 25.29 * 4
Duration: Instantaneous
Recharge Timer: 12s
Activation Time: 6s
Brawl Index: 1.9444 * 4
Recommended Slotting: 4 Dam, 1 InterruptRdx, 1 EndRdx
___________________________________
Aim
This provides a large accuracy (66%) and damage (50%) bonus for ten seconds. This is a must-have, it gives you the ability to land Irradiate on just about anything, and increases the damage of the first 2 attacks after that you use (Or any attacks you can cram into 10 seconds) and has great synergy with Choking Cloud.
Endurance Cost: 5
Duration: 10s
Recharge Timer: 90s
Activation Time: 1s
Recommended Slotting: 1 Rech
___________________________________
Cosmic Burst
Lime Cream Puff of Doom! This power is high damage and a Mag 2 foe disorient. With a single disorient enhancement and Hasten/AM a +3 boss can be just about perma-stunned. You may consider sparing a slot in this power for accuracy if you rely on it to stun things for you all the time. It has no innate accuracy bonus, but provides an innate defense debuff of 10% for 5 seconds.
Endurance Cost: 12
Base Damage at 50: 76.62
Duration: Instantaneous
Recharge Timer: 20s
Activation Time: 3s
Brawl Index: 5.8889
Recommended Slotting: 1 Acc, 5 Dam or 1 Acc, 4 Dam, 1 EndRdx or 1 Acc, 4 Dam, 1 Disorient
___________________________________
Neutron Bomb
You make a giant ball of radiation and launch it like a catapult in a high arc towards your foe. It splatters on the ground and explodes in a big mushroom cloud. Fun to watch. This is your ranged targeted AoE attack. This does slightly less damage than Irradiate, but has a faster recharge and, as stated, range. It has an innate accuracy bonus of 10% and provides 10% defense debuff for 5 seconds.
Endurance Cost: 18
Base Damage at 50: 32.52
Duration: Instantaneous
Recharge Timer: 16s
Activation Time: 4s
Brawl Index: 2.5000
Recommended Slotting: 5 Dam, 1 EndRdx
___________________________________
Atomic Blast
A very situational power. While it does extreme damage (enough to kill many +2's or even +4's in some cases with Enervating Field), it's rare that you'll need this unless you're running out of endo - you'll often do nearly as much damage with a couple rounds of Irradiate + Neutron Bomb, and Atomic Blast WILL drop your toggles and leave you with no Endo and very little endo recovery. On the upside, most things that weren't killed by it will be held for a few seconds, giving you time to either pop a CaB and drop Irradiate/Neutron Bomb or run away. It has an innate accuracy bonus of 30% and a defense debuff of 30% that lasts 15 seconds.
Endurance Cost: 24
Base Damage at 50: 41.56smashing, 72.28energy, (54.21energy * 1-3)
Duration: 10s
Recharge Timer: 6m
Activation Time: 3s
Brawl Index: 3.1950s + 5.5556e + 4.1667e
Recommended Slotting: 4 dam, 2 Rech
___________________________________
___________________________________
PART III - ANCILLARY POWER POOLS
___________________________________
The Ancillary Power Pools allow you to take your defender several different directions. All of them give you a couple powers which work well with the Rad set; I chose Dark Mastery, but any would be a good choice. The Psychic set has the least natural synergy with Rad/Rad, but there is still some (stacking holds)
___________________________________
___________________________________
Electricity Mastery Pool
___________________________________
Electric Fence
A decent-damage Single-target Immobilize. Damage-wise this is similar to X-Ray Beam with a faster activation, but is a DoT attack. IF you take this, add it to your attack cycle instead of Neutrino Bolt. Also, this power has -knockback.
Endurance Cost: 11
Base Damage at 50: 7.22 * 5
Duration: 22 seconds
Recharge Timer: 4s
Activation Time: 1s
Brawl Index: .5556 * 5
Recommended Slotting: 1 Acc, 5 Dam
___________________________________
Thunderstrike
A good-damage power with a small AoE, which often disorients foes. When the AoE is present, this power deals only very slightly less damage than Total Focus, but disorient is not guaranteed.
Endurance Cost: 34
Base Damage at 50: 93.95 + (24.98 AoE)
Duration: Instantaneous
Recharge Timer: 40s
Activation Time: 4s
Brawl Index: 7.2222e + (1.9204)s

Soul Drain
This power ROCKS! It's not quite a self Fulcrum Shift, but it's close, and provides an accuracy buff. This has great synergy with... everything, and works wonders with Choking Cloud. With Hasten + AM, 4 SO Rech will allow it to come up just about as fast as Aim with 1 SO Rech - sufficient to use at the beginning of most every fight.

___________________________________
PART IV: BUILDING THE BUILD:
___________________________________
This is not just a guide for my build. I'm providing three different builds here: 1 up to 29, a Respec build from 30 to 39, and a Respec build for 40+
___________________________________
From 1 to 29: It's hard to get all the powers you want, because all the great rad powers are stuffed in the beginning. However, play it something like this:
Level 1 (Starting Primary) : Radiation Infection /HitDeb
Level 1 (Starting Secondary) : Neutrino Bolt /Acc
Level 2 : Accelerate Metabolism /Rech
Level 3 : Neutrino Bolt: 2 Dam
Level 4 : Irradiate /Dam
Level 5 : Radiation Infection: 2 HitDeb
Level 6 : Enervating Field /EndRdx
Level 7 : Enervating Field: 2 EndRdx
Level 8 : Radiant Aura /Heal
Level 9 : Neutrino Bolt: 1 Dam, Irradiate: 1 Dam
Level 10 : Assault /EndRdx
Level 11 : Irradiate: 1 Dam, 1 EndRdx
Level 12 : Hasten /Rech
Level 13 : Radiation Infection: 1 HitDeb, Hasten: 1 Rech
Level 14 : Super Speed /RunSpd
Level 15 : Accelerate Metabolism: 1 Rech, Hasten: 1 Rech
Level 16 : Swift /RunSpd
Level 17 : Accelerate Metabolism: 1 Rech, Hasten: 1 Rech
Level 18 : Health /Heal
Level 19 : Accelerate Metabolism: 1 Rech, Hasten: 1 Rech
Level 20 : Stamina /EndRec
Level 21 : Stamina: 2 EndRec
Level 22 : Proton Volley /Dam
Level 23 : Stamina: 2 EndRec
Level 24 : Aim /Rech
Level 25 : Neutrino Bolt: 1 Dam, Irradiate: 1 Rech
Level 26 : Hover /Fly
Level 27 : Hover: 1 Fly, Stamina: 1 EndRec
Level 28 : Cosmic Burst /Acc
Level 29 : Cosmic Burst: 2 Dam
This should serve you more-or-less well in the early game when slots are at a huge premium.
From 30 to 40: You're beginning to get some slots, but still not enough for all the wonderful powers you'll get.
Respec at 30 into something like this... you're starting to see your build emerge. Order of slots aren't important for a respec build because you don't lose slots when exemplaring down, only powers. Often the build is limited by how much endo it has; this will help conserve lots.
Slot[01] Level 1 (Starting Primary) : Radiation Infection /HitDeb,HitDeb,HitDeb,HitDeb,HitDeb,EndRdx
Slot[02] Level 1 (Starting Secondary) : Neutrino Bolt /Acc,Dmg
Slot[03] Level 2 : Accelerate Metabolism /Rchg,Rchg,Rchg,EndRec,EndRec,EndRec
Slot[04] Level 4 : Irradiate /Dmg,Dmg,Dmg,Dmg
Slot[05] Level 6 : Enervating Field /EndRdx,EndRdx,EndRdx,EndRdx
Slot[06] Level 8 : Radiant Aura /Heal
Slot[07] Level 10 : Hasten /Rchg,Rchg,Rchg,Rchg,Rchg,Rchg
Slot[08] Level 12 : Swift /RunSpd
Slot[09] Level 14 : Super Speed /RunSpd
Slot[10] Level 16 : Proton Volley /Dam
Slot[11] Level 18 : Health /Heal
Slot[12] Level 20 : Stamina /EndRec,EndRec,EndRec,EndRec,EndRec,EndRec
Slot[13] Level 22 : Aim /Rech
Slot[14] Level 24 : Choking Cloud /EndRdx
Slot[15] Level 26 : Stealth /EndRdx
Slot[16] Level 28 : Cosmic Burst /Acc,Dmg
Slot[17] Level 30 : Lingering Radiation /EndRdx
Then continue Building to 40:
Level 31 : Cosmic Burst: 3 Dam
Level 32 : EM Pulse /Rech
Level 33 : Proton Volley: 3 Dam
Level 34 : Proton Volley: 2 Dam, Cosmic Burst: 1 Dam
Level 35 : Neutron Bomb /Dam
Level 36 : Neutron Bomb: 2 Dam, Choking Cloud: 1 Hold
Level 37 : Neutron Bomb: 2 Dam, Choking Cloud: 1 Hold
Level 38 : Hover /Fly
Level 39 : Hover: 3 Fly
Level 40 : Hover: 2 Fly, Choking Cloud: 1 Hold
That'll get you used to tactics later on. At 40, of course you figure out what you want to do for Ancillary Pools.

___________________________________
___________________________________
PART VI: PLAYING THE BUILD
___________________________________
You'll be using most of the same tactics from lvl 1 onward. Open the battle with Radiation Infection, and Enervating Field.
___________________________________
You'll take less damage less often this way. Although it will be greatly more effective at lvl 22 than at lvl 1, it's a tactic that will serve you well in the beginning. You will get hit about as much and for as much damage as any tanker at the low levels, but can heal yourself as regularly as you like.
After you get used to that, you'll learn to use terrain to group up your enemies, clearing line of sight, and drawing aggro onto your terms. The key here is tight groups of enemies; any outside your debuff cloud will be doing their full unmitigated damage to you. This is unacceptable. Think about this:
A minion will hit you about half of the time. If he does 100 damage a shot, that's 50 damage a round on average. If he has nine buddies, that's 500 damage a round on average.
Your maxed-out RI + EF + LR combo can reduce that damage a lot. Stack 2 LR's on them and their attack rate goes down to 1/4. That means 100 damage every 8 shots instead ot 2 - 125 damage per round average.
Then your maxed-out defense will take that 125 damage and reduce it. Because instead of hitting half the time, they'll hit 1 in 20. 100 damage a shot becomes 100 damage in 20, per attack. And since they only attack once in 4 rounds (because of LR) it's really 100 damage every 80 attacks.
Then EF reduces that damage by 35%. 100 damage becomes 65 damage per 80 rounds.
You've reduced 500 damage a round from ten opponents to a mere 8 damage per round.
As long as you can keep them clumped together. If you can't, well, you're just as squishy as the rest of the squishies.
After you reach the goal build (lvl 48+) you will toss up RI and EF, waltz into a mob with Choking Cloud running, then hit Aim + Soul Drain and then cycle Irradiate and Neutron Bomb till all Lt's and lower are dead. Then you'll switch to Cosmic Burst-Proton Volley-Cosmic Burst for finishing off the bosses. If there is some kind of sticky debuff or DoT that prevents you from using Proton Volley, use Irradiate + Neutrino Bolt while Cosmic Burst recharges. If the debuff is being generated by a boss (like a Death Mage's Darkest Night), it'll go away when you hit them with the 2nd Cosmic Burst. You can then start the Cosmic Burst-PV-Cosmic chain as they will be disoriented again just before you use your Snipe, every time.

PART VII: TIPS AND TRICKS
___________________________________
Your toggle debuffs are a constant tick, which will interrupt all interruptible attacks all the way from embalmed cadavers exploding and mortificators rezzing baddies up to Sky raiders laying forcefield generators and crey medics healing.
If you put target something and move behind something you could jump over to gain line-of-sight, you can cue RI, jump, and when you land, RI will go up but will often draw no aggro. Then you and your buddies can enter the area safely under stealth.
When teaming, always anchor your debuffs on Lieutenants or, preferably, Snipers (who will never run away) if engaged near them. Single target guys (like most scrappers and some blasters) will almost always kill bosses first. Likewise, AoE guys (most blasters and some scrappers) will kill the minions first. Lt's are usually the last to die. You will appreciate the results of training your regular groups to do this when you get to fighting Nemesis soldiers, whose Lt's give out Vengeance when they die.
Always make sure AM is up before a fight. Having Perma-AM isn't always the wisest choice because sometimes you will need to recast it at crucial points during a battle, often depleting yourself of endo as AM and HAsten wear off at the same time and you need to have endo left over to recast AM. Running out of endo will often be lethal for you, so I recommend you don't put up AM unless you're about to run into battle. Knowing you'll have it for the full two minutes from the beginning of every fight is priceless.
I'm looking forward to seeing comments and suggestions.
NOTES ON PHASE SHIFT:
Phase Shift's recent fix (so you can't turn on toggles while PS'd) was NOT a nerf to toggle defenders. Phase Shift can still be used to absorb an alphastrike.
Have PS and Super Speed on, walk to the center of the mobs, and turn off SS. All the mobs will shoot you. AFTER this, turn off Phase and put up RI while their attacks are recharging.
The power most affected by the Phase Shift change was Choking Cloud, which now takes longer at the beginning of the fight to hold the mobs (since it doesn't easily grab everything until after your RI+Irradiate goes off).
Phase Shift+SS is the preferred method to go Invis when CC is running because PS turns CC's effect off without making you wait for it to recharge and need to activate it again. The power Invisibility will also do this, but leave you vulnerable to sniper attack and mobs that see through invis. In this way, Phase Shift can be used as the on/off switch for CC.

Def Epic Pools Guide
Rad Blast:
Cosmic Blast is excellent. Get it!
Irradiate also rocks, nice PBAoE, with a good defence debuff that lasts a long time.
X-ray beam is green laser eyes! Nuff said.
Proton Volley has a great sound, but it's a snipe and I don't think that works too well with some of the other rad/rad powers, which require you to be in the thick of things.
Neuton Bomb and Electron Haze both have long animation times, so I dropped them.
Atomic Blast is awesome fun, but leaves you very vulnerable to anything left standing. It sucks in PvP.
Radiation Emission
Get the 2 debuff toggles. RI, chuck lots of acc debuffs in. EF is a very expensive toggle, 2 or 3 end reduction SOs make it tolerable. They also recharge a bit too slowly, so I put a recharge enhancer in each.
The heal kinda sucks now, but still worth taking and slotting heavily.
Accelerate Metabolism! Great! Get it and 6 slot it. 3 recharge, 3 end recovery.
Lingering radiation is good if you slot it heavily. Otherwise, don't bother with it.
Choking Cloud is very very good with a few Hold Duration SOs in, especially when you combine it with Aim. In PvP it won't be so great, since it only tries to hold every 5 seconds and it's low magnitude too.
EMP is totally awesome! For PvE slot for hold duration. PvP you can slot for endurance drain which is a nice trick (thanks to Cherry Fusion for that one!)
Edit: A few of the values in that guide above are incorrect. Specifically, I see lingering radiation - it's recharge is very long now, something like 80 or 90 seconds, and it's duration is shorter. Also, the recommended slotting is all out of whack for ED. Having said that, I did use it for refererence with Irradiator, but that was back in I4 and I5. It's still useful, just remember it's not entirely correct anymore.

Check me out, I'm a celebrity! Hehe.
I was gonna make an evil Irradiator (anyone who's seen his outfit would agree that he looks quite villainous as it is!) on defiant as a corruptor, but some bugger has gone and taken the name! Curses!

Yep, youre pretty memorable. and in any case since you lead the team i was on for the last union hami raid, and i got a hami-o, i thought you would have some good advice.
This has probably been asked before, but as i have a mm now at lvl 19 i quite fancy starting a corruptor.
Ive looked at rad/rad and it seems a good combination powerset.
Any comments please.
