Took him to 4/55 a while ago and thinking to 5/65 just to get my AVENGERS collection at 5/65 OG THOR,CAP (IW) and Dr.strange for Nostalgia and some fun. he is far from anything OP in his class or anyother. (Doom, SS,MS,magik,voodoo still far superior,) i think i'd put him on same level as Diablo ,both has respactable Regen but besides that not much going on with them, and well i am sure i wont be able to move on act 6 100% in next 2 years and not really wanna go through that pressure and stress inducing stuff, so Decided to go the "FUN" route in the game, unique rankups and weird teams for AQ and AW and questing content, and well civil war variant might give avengers some good time.
