My only issue with a dogpile scenario is that they're dealing with a dude strong enough to ragdoll any of them he gets his mitts on. Which means while three of them are trying to coordinate attacking him, he may have grabbed Colossus or Rhino and be beating the others over the head with his victim's body. Or just be punting people away from him as fast as they come (Ares having the skill to avoid this, I figure, but I'm less sanguine on Ben or Piotr doing so against an enraged Class 100).

Not saying it's not possible, just saying it's a whole lot more difficult when the other guy is more than twice as strong than anyone else here and looking to put the hurt on anyone getting in his face.
