It's not all SF games. Brittle bruisers like Yun or Ibuki are stand outs in 3s and 3s has variable health, painfully apparent in the case of Akuma, but SF2 and iirc 4 or at least 5 had set in stone values. I don't usually like variable health as a design trait except to give grapplers more chances or to counteract absurd offensive traits.
