It needs a nerf, yessir.I'd like it to be more focused around ambushing rather than just hitting M2 in the middle of a fight and instantly getting full health and being invulnerable to almost everything for a few seconds. I know you can run away from a Phlog Pyro but it's still annoying.So something like, remove the damage resistance but make the taunt make so sound and perhaps be slightly faster, so you have to get to a safe place to activate it, then rush out and ambush everyone.And for gods sake increase the damage needed to start the boost.
