Ice/Pain.
Great healing.
Team Buff.
PBAOE debuff.
Pain is very strong, it gets knocked a lot but it's a great set and doesn't require a lot of slots.
Painbringer is fine with only a recharge, and your heal toggle is great with only 2 heal ios, since it costs so little end already. Pain is also a very light activation set, which leaves plenty of time for blasting. Your team buff lasts a long time and enemy debuff power is on decent timers, which leaves only firing off heals when needed.
If you are looking for a set you haven't tried, I would strongly suggest looking at pain.
I've considered Pain over and over and I always seem to lean away from it. If you've got experience with Time Manipulation I'd like to know what you think of it. Those seems to be the two contenders for my remaining character slot.
Time Manipulation is flat out amazing. I love this set beyond all reason. I am a controller fan at heart and this set screams it.
Ice/Time will be very strong. The only thing about TIME is it can be very slot intensive to get full benefit out of and is very clicky. Seriously time is one busy set. The heal isn't strong but works really well when used proactively as you start to take damage, the initial debuff is vital for some of the juicer tidbits. The other problem with time depending on your view, is it almost always screams to be paired with Power Boost or Power Build UP, which limits your epic/patron powers. I don't think they are really needed but the benefit they provide is very VERY strong for a set like time. SO it is tough to argue against them.
Time is IMO one of the best jack of all trades sets bar none. It puts other sets to shame and really does make the case for giving buffs to sets like trick arrow and others. AOE heal over Time, AOE hold patch mostly for debuffing, AOE debuff, Huge +DEF click, 2 powers with -regen, a potential mag 4 stun, and a nice debuff toggle, Chrono Shift is just icing on a stellar cake. I don't even bother slotting it with anything other then recharge tbo, as I don't find I need the minor heal/recovery buffs.
Add in all the mitigation goodness, damage of ice and you would have a very strong toon but a very busy one and potential very blue bar piggy. If your looking between Pain and Time I can't honestly say go Pain instead of time, even tho I want to. TIme is a set that must be played to behold, then try pain once you've pimped out time. Pain is much less active tho and is still a very solid set that merits something to look into, depending on your personal play preference. I am having a hard time myself deciding between Psi/Pain and Psi/Time as I've not yet made time on a corruptor. I have 3 trollers, 1 MM and a defender all rocking time, and the defender is rounding 40s so I am holding back a bit on a time corruptor or atleast I'm trying to resist the urge.
Can't go wrong with either! But yeah try Ice/Time 
that just sounds too good to pass up.
I have to say I LOVE my Ice/Storm.
Dropping Freezing Rain and then Ice Storm on top of it is just fun. I also love the synergies it has (lots of slows and Ice/ has some -ToHit aswell as storm)
If you haven't tried storm before I reccomend it, throwing up your lightning storm and tornado (with the OF proc) then using Burnout and getting another storm and tornado, just, insane. Be even better with the i24 changes and dropping your Blizzard twice
It also has the added benefit of Storm not being an overly busy secondary, your Steamy Mist and Hurricane are on and everything else is drop and forget about it. It means you also only have to build for ranged defense because things jut don't get through that Hurricane. And if you're worried about surviability due to its lack of self heal, don't. Nothing will be standing to hit you anyway.
I need suggestions on what to pair with Ice. I've already got a Kin, Cold, Dark, Storm, Trick Arrow, and Rad. I'm willing to make another of any of these if I find the build solid enough however I was hoping to make something I've not yet played before. My main reason for an Ice primary is because I've never played it and Blizzard will be epic with the new i24 changes. Thank you a head of time for all suggestions or comments.
