I would personally recommed Fire/dark.
Fire has good damage while dark has a heal, slow, debuff and stealth power and finally Fluffy your pet!
Rain of fire on tar patched enemies is quick death for a mob.
Altitus doesnt have a cure just more alts
Hello and welcome,
First off, after trying out all the Arctypes myself I have found that Corruptors really do do better in teams than all of the rest, yes some Solo slower than others but for gameplay the Corruptor AT excells at team play. But they can solo ok to, you just have to look at the secondaries that will help you the most. From that the Radiant Infection, Dark Miasma and Kinetics sets offer probably the best ways to do this. From the primaries Energy Attacks will give you the best initial Single target attacks, being able to take the core 3 by lvl 6, but these annoy teams sometimes because of their additional knockback attacks. Ice comes with a nice hold in it by lvl 8 and 2 early decnt attacks and a nice location based AoE which when used with other powers that slow opponents can help you a lot.
Dark hyas an early sniper attack, which can help with soloing by pulling enemies, and fire has an early AoE in the form of Fireball. Assault rifle is nice if you like guns, and has some nice AoE's, but these can cause knockback to, and Lethal damage it does is one of the most commonly resisted damage types in tha game. Sonic attacks debuff the enemy by reducing their damage resistance for a short period of time.
Thats just a brief overview, when I started out I found that I tried out many differant types of character for a while up to lvl 10 to get a feel for them, many I didn't like, and these can be deleted and replaced before you have spent to much time on them.
When you team you can generally always find one as a Radiantion Infection or Kinetics to, these are always in demand, and their powersets can help you solo ok to.
So get out their, experiment and above all have fun.
Good Luck 
Thank you for the quick response!
Im going to try out some fire combos then
I would like to recomend Ice/rad Emission -
Ice Primary, very fast animations, bit endurance heavy but can be countered by AM in rad secondary
Hold (Freeze Ray) at lvl 8 - 2 applications of this will hold a boss,
Ice Storm (aoe) and Blizzard (love this power - ranged targeted aoe, so no running into mobs - will drain your endrance but anything caught in it will be constantly knocked over)
Aim + Ice Storm + Blizzard combo has got to be witnessed 
Rad secondary: very simple to use secondary - few higlights of why i like the set:
Radiant Aura :heal,fairly fast animation (no target required to activate) so you can use it on the run
Rad Infection, and Envervation field - no acc check required on these, lower targets acc, defence and resistance
- great for using on troublesome Boss. Elite Boss etc
- Just make sure you dont kill the target annchor till last
Acelerate Metabolism, Uber buff teams will like you for this - Great pre stamina endrance booster
Lingering radiation - will slow mobs to a crawl, reduces their recovery rate too
Mutation - for rezzing and boosting dead brutes

As I have seen you have decided the primary set, i would give u an advice about which set should be your secondary... KINETICS...
You will see how your team become a killing machine with all the powers of this set:
* Probably the best heal in the game for a supporter toon, since u dont need to get dirty in melee to heal ur comrades.
* Nice buffs, your m8s will beg for your buffs, i swear it... No comments on this, you should taste them all...
* Nice debuffs, the -end in transference and transfusion, and the -speed -rech in siphon speed can change the tides of a battle...
* Some tools like repel and SJ without supressed time for all your team (inner reduction)...
Oh yeah, you cant go wrong with that secondary...
For a good primary which sinergizes good, I have seen almost all the primaries sets paired with kinetics, so its up to u... I went for ice, and Ive never regret it...
Cheers, and enjoy it!!
Oh, hmmm, I would say that kinetics is not that good for a new player as it is one of the more advanced sets that can be quite taxing on the player´s endurance if played well.
However, /kinetics is a tremendously powerful set, so I guess it is still worth a try, especially when paired with ice/, fire/ or sonic/, depending on if you want to be single target killer and slowmaster, AoE nightmare from hell or howling mad shield eater and AV killer.
I can also recommend /radiation as secondary set for the great debuffs and other useful stuff. Ice/ goes really good with this one. Fire/ should also work, but depending on your power choices your attack chain might feel a little bit slow.
If it has eyes, you can blind it, if it has blood, you can make it bleed, if it has a mouth, you can make it scream.
Welcome!
Ice / Kin is my choice sorry - Really good solo or in team PVE and awesome in PVP
All Ice attacks are -speed and -recharge debuffs
and Kinetics just rocks as The_DefUser said people will love you
thats my choice anyhow
have fun try out a few builds see what you like, remember your character is your character. Play the game how you want to play it not how other people want you to play it.
Hi there. Im about to start playing CoV and I wondered if
anyone could help me out. Im considering Corruptor as class
and would like to be flexible between solo and grouping.
Solo mostly to grind some, and to learn the flow of the game
so I dont make a complete idiot of myself
Been looking through the guides that are posted, but most
seem to be totaly focused on group play and "not really a
good solo choise".
Anyhow, any help appriciated!
