Debuffer

Debuffer's basically a tank-style Dude with a few long-ish term debuffs (slows, attack speed slows, things that don't necessarily do damage but are annoying) then he has an ultimate/super/whatever you wanna call it where he channels for a couple of seconds and all debuffs explode, dealing AoE damage and reapplying to anyone who got hit by the AoE (but not the source person)

e.g. A B C

B has debuffs, A and C are close by, Debuffer uses his detonation move, A B and C all take damage, but only A and C end up debuffed with whatever B had to start with.

Possible skills:

Slow

Damage decrease
