 I'm just worried that there'd be too many characters capable of self-sustain (such as healing). (Hadouken some dude 5 times, only to have him regenerate. Hadouken the other dude, and he regenerates as well. Hadouken another guy, and he doesn't get healed, but five people heal him anyway, making it a method of sustain. Time to Hadouken myself, but I regenerate as well)

Problem is regeneration is the biggest safety net ever xD You say be 'combat ready' and regeneration gears up to multiply. It's effective after all, as you posted above :P
