Carnage Scissor is ass, and I main hakumen. That says a lot, unless you're doing; a sure-fire reversal at point blank range (invincibility frames), badly timed projectiles, to get/gain health/advantage, or a kill because of its minimum damage, it's ass. And exactly that's why he has the best dp in the game, only other ones that can compete with it are hotaru and rehhyou (though that one is controversial).
Why did they take out additional damage for carnage scissor when you're in BK btw? it actually made it less shitty when it had that (in my view).
