what now?

Hi.A long while ago,I set myself the task,of getting one of each archtype to lvl 50.On both cov and coh.
I've got all the one's on coh.Now it's cov time.
I've got a dom,brute,and widow to 50 so far.I'm doing a mm atm,at lvl 30 now,so looking for what to do next.
I chose corruptor to do next.
As I mainly team,not solo,does anyone have a good choice for powersets to take,that are good for teaming?

All corruptor secondaries bring something useful to teams, but some are more solo-friendly than others. Among the ones which are better for teams I'd say cold, sonic and thermal since they have several ally-targeted buffs. Kin, rad, storm and dark are also very good for teams, but in addition offer good options if you're soloing (cold and thermal too, but only at higher levels). It depends a bit if you don't mind keeping your team-mates shielded, or if you prefer anchored/location-based (de)buffs, etc. Storm can be annoying for some teams if it's not used properly, but is a great set once you master it. Traps is the only set I haven't played at high level (past Tier 9), so I won't comment.

In terms of primaries, all are fine for teams. Some have slightly more AoEs which can be handy, but look also at the secondary effects which can benefit your whole team (e.g. -res, -def, -tht, slows, etc.).

cool.thanks for the advice.much helpful.
