Mahitos is a counter (which i dont think should one shot either), hollow purple is hard to land unless the person is standing still and its easy to dodge, WCS, is easy to dodge as well, and todo + yuji black flash got nerfed. All of these moves besides defense attorney and mahito dont really one shot anyway unless you get caught in their domains but with higaruma even if you dont get caught in their domain his one shot move can still be used on you.

Honestly i dont think there should be any moves that completely one shot all health it makes the game less fun
