The guide in my sig has the majority of what I have to say about Storm. Although the guide uses Defender numbers, there isn't that much variation between the two. Corruptor numbers are 80-100% of the Defender numbers depending on the power. The only choice in the build I might question is air superiority, especially if you have a vet attack to fill out your attack chain (Freezing Rain means you don't need to worry about the unenhanceable accuracy much)

And I would definitely op for power sink as Storm is very endurance heavy.

The bigger mistakes you might make on the build are in slotting.

1) Your instincts are correct, don't slot end mod in your attacks except for power sink.
2) In general don't slot Slows, the numbers are large enough that Snow Storm and Freezing Rain will floor most things movement and recharge(which slow doesn't enhance anyway)
3) Recharge in Freezing Rain (not slow or debuff, procs are good)
4) Damage and recharge in tornado (not stun or debuff, procs are less good)

Hope that helps to get you started.

I'm a little confused about what we're deciding between.

Are we deciding between, slot RoA with a proc, or leave the last slot empty? In which case, clearly the slot the proc...in fact given the choice between leave it empty or slot something, slot something is almost always the right answer.

But in all seriousness though, if you're going to 6 slot RoA, then the javelin proc, if you can afford it, isn't a bad way to go.

However, what's more relevant is what power is losing a slot so that RoA can get another slot? It might be more beneficial to put that damage proc in a faster recharging AoE that you use more often, or slot for that extra recharge bonus somewhere, or try to hit the defense soft cap to some type. Basically it depends on your play style and current build.

Alright, I don't have time to respond to the full build at the moment, so some initial thoughts to get you started (more thoughts available in the guide in my sig as well).

1) Gale is not a damage power. Unless you find you actually use it (I doubt it) it is currently a 5 IO 6.25% recharge bonus mule. There are so many places to use those slots. Stick an accuracy in there, and move on

2) Snow Storm is over slotted. (Also, technically an exploit, but not one that is likely to get fixed anytime soon since it's been around since the start). Snow Storm and Freezing Rain will put anything at the slow cap, 3 IOs is overkill. stop at 2.

3) Freezing Rain is not a damage power. If you want to deal damage with it, slot procs. It is a debuffing power. You want Freezing Rain up as often as possible to increase the damage you deal so slot it for recharge. (Achilles' heel proc is also nice along with the damage procs)

4) Stealth is currently a set mule and will not stack with Steamy Mist. Consider weave instead as something you might actually use on occassion, or better yet, an endurance recovery power.

5) I predict endurance trouble (especially if you're not going cardiac). Consider Miracle in Health, and Performance Shifter +end in stamina along with 2 endurance IOs.

(And....I'm out of time but one last one)

6) Tornado is a damage power, not a debuffing power, and slot it as such.

the /vault command is nice too

Wow...very nice.

I will say the costumes look a little fancy for low level CoT, but for the high level CoT I think they're great!

Looking good Grae just a couple more options:

I don't know how essential it is to have damage in Explosive Arrow, but there is often little enough AoE damage, that you will find you are virtually invincible with just ranged soft capped and could afford to lose the AoE bonus with minimal impact on performance, but not being familiar with Archery, I can't assess the relative importance.

Because you are now over the ranged defense soft cap (which can be desirable since the cap is 59% in incarnate content, and gives you a tiny buffer against defense debuffs) you could also afford to swap the defense/recharge in Steamy Mist for an LoTG recharge, and then drop invisibility and pick up conserve power. That still keeps you above the 45% soft cap.

Also, I've assumed that you were avoiding hasten for stylistic reasons (aka glowing yellow hands) but you could also consider dropping stealth for hasten if you swap out invis.

Alright, I still don't see a Steadfast Protection 3% defense IO anywhere. Any particular reason why?

If you slotted that (either take a slot from health, hurricane, or a 6 slotted thunderstrike, or change your slot in tough and stick a zephyr in Super Jump for KB protection) you could remove the Force feedbacks from explosive arrow and replace them with Positron's Blast for the 6.25% recharge bonus. You could also pick any power that you have 6 thunderstikes in and replace it with 5 decimations for the 6.25% recharge bonus. (If you're keeping 6 slots you could include the devastation chance for hold proc).

I would probably also sacrifice the Detonations in Rain of Arrows for Posi Blasts for another 6.25% bonus. Those changes would leave you at 45.1% ranged defense and 40% AoE.

I have never found tactics +perception to be insufficient, so I would stick endurance reducers in there if anything (unless you're simply planning on not running it, in which case that's fine).

I would probably swap out Gale or invis for conserve power as well, but your call.

Finally, even with cardiac, I would try to stick the miracle in health.

I don't have acccess to mids at the moment, so this will be an overview with some thoughts:

Going for smash/lethal/ranged/AoE defense is generally overkill. I find that you will get more survivability if you just soft cap either positional or typed and then go for some resistance with your shield (or go for smash/lethal with scorpion shield and then go recharge), although because you have Hurricane to handle melee, I find going to the positional approach to be more beneficial.

Looking over your build I don't see a Steadfast Protection: 3% defense IO anywhere. You should pull that in and use the opportunity to get rid of some of your smaller set bonuses. For example, do you really use Gale? And if so do you actually find you need more KB from it? I would slot accuracy and damage procs in Gale: damage/KB in gale seems like a complete waste to me.

Freezing Rain: with the 3% defense IO you can drop the shield breakers from FR. This power wants recharge. After recharge a little achilles' heel proc can be nice, as can damage procs.

Hurricane: Would have to pull out Mids to see how many 5% bonuses you have, but for Dark Watchers in here can be very nice (I would bull the two slots from Gale).

Tornado: Against single hard targets Tornado can be massive damage dealer, so I would slot for damage long before slotting for defense debuff (and depending on how often you use it, recharge and end reduction).

Stealth and Steamy Mist are wasted since you can't actually run them both at the same time. If there is no other power you want, then keep stealth as a LoTG mule, but recoup the slots to stick somewhere else.

Health: Not crazy about 6 slotting health for the numinas...should be somewhere better to get that bonus. (I'd probably 6 slot Tornado with Blood Mandates since you're going for AoE and Ranged defense) and then you can stick the Miracle unique in health as well.

Some of those thoughts might change after I have a chance to play around in Mids, but that's a start. If you're intersted in knowing more about my thoughts on Storm Summoning **points to sig**

This build is certainly more reasonable in price. You haven't gone for crazy amounts of recharge or defense so this probably won't feel "epic", but you should notice a significant improvement in your performance.

Some thoughts:
Chillblain: I would stick another slot in there and go with 5 decimations for the 6.25% recharge bonus.

Block of Ice: Since you don't have significant defense bonuses, consider swapping out 4 lockdowns for 4 Basilisk's gazes and 7.5% recharge. However, beware that this is one of your main attack powers, so you may want to consider putting more damage in there than hold.

Freezing Rain: I would consider dropping the pure defense debuff IO for a damage proc, but this slotting is also fine.

Hurricane: You will get more milage from 4 dark watcher's despairs here for the easy recharge bonus.

LS: Force Feedback proc is a waste here. It will only have a chance to fire on you when you summon LS and otherwise will have no impact. Too long a recharging power with too low a chance to fire, in my opinion.

Health: I would stick the miracle proc in here as well, I still predict you're going to want all the endurance you can get.

I'm going to agree with Morganite here. You are going to want to spend some time looking at the market to get a sense of how much some of those IOs run for. You have a couple that generally sell for 2 billion or more in that build. Although those IOs are now purchasable through other means you are still looking at 60-70 empyrian merits, or 35 Hero Merits. Also, often those sets do not have the best set bonuses, even though they are the most expensive. If you want to spend money on an expensive build, I would suggest sticking a LoTG proc in every power that will take one before splurging on PvP IOs.

Defense becomes more valuable as you have more of it, so unless you are building for the soft cap (that's 45% defense in non incarnate trials) I would say 2 billion influence for 3% defense is not worth it.

In general to be truly powerful with IOs you should try to maximize either recharge, or defense. If you are truly planning on PvPing, then hitpoints are essential as well, but they won't make you feel particularly powerful in PvE. My recommendation would be to look at prices, to get a sense of price point you are interested in, decide if you are more interested in defense (ranged goes well with hurricane, smash/lethal goes well with arctic air) or recharge (more LS, FR, Tornado, Glacier (which you don't have))

I don't know how close to this build you are running right now, but with three leadership toggles, arctic air, steamy mist, sharkskin running, I suspect this build is rough on the endurance and I hope you're planning on going cardiac. (If you find that hibernate is enough to solve your endurance issues, then great!)

Some thoughts on slotting to help you along:

Chillblain is one of your primary damage powers, slot it as such.

Snow Storm: You have so much -recharge that the -recharge proc in Snow Storm is wasted (especially on an ice troller). Also consider how much you use Snow Storm. I find that I tend to use it fairly rarely at higher levels, so this would be over slotted for me. If you use it on every battle though, then great.

O2 Boost: Heal Procs (with the possible exception of the Panacea) should always go in Stamina. You don't want to be reliant on having someone/thing to heal to get the bonus. Jack dies, and you aren't getting any significant set bonuses to make this worthwhile. Consider Doctored Wounds for the recharge bonus.

Fly: The stealth proc can go in sprint, don't waste a slot on it.

Steamy Mist: This is probably an 8+ billion inf slotting. You may want to reconsider

Freezing Rain: The most important thing in Freezing Rain is recharge. Analyze Weakness is not worth it in Freezing Rain in my opinion since FR should let you hit just about everything anyway. A good proc for FR is the Achilles' heel proc.

Tactics: Chance to build it up is probably the most frustrating thing in tactics. It always seems to fire when you are between fights. I was never happy with the proc there.

Hurricane: the Force feedback proc is a waste unless you are going to run hurricane all the time. And if you're going to run hurricane all the time, you need more endurance in it. Deflated ego is also basically worthless since you don't have a reliable way to sap endurance. If you use hurricane consider 4 slots for Dark Watchers. However, Hurricane conflicts with Arctic Air, so if you use Arctic Air it may be you choose not to take it. In which case, I suggest possibly swapping out one or the other for Glacier.

LS: Devastation Hold is better than the stun since it has a higher percentage, especially since you have other holds to stack with it, you don't have another reliable stun (since you didn't take thunderclap). I'm not even certain the Decimation proc will work due to the time between lightning strikes. Still need to do testing on that.

Waterspout: Like tornado this power is autohit, so you don't need accuracy. If you enjoy using waterspout, then you should consider slotting up tornado as well and using both of them. Especially since you have KB suppressing immobilizes. (If you like that strategy, consider frostbite. I would drop one of the leadership toggles for it).

Brawl: wow...that's a waste of a hecatomb....

If you're interested in seeing more of thoughts on Storm Summoning you can read my guide. The numbers are for defenders, but controller numbers are 100-80% (depending on the power) so most things apply to controllers as well.
