To be honest, this would be a lot more fair. KD has immunity, only eats away 3M, is completely nullified by MA and it still needs to crit to inflict KD 'AFTER' flatfoot.
This is completely balanced, and the max it could do would be the most annoying shit to fight against if you're not prepared for crits or KD. Aside the damage on it being a poop.

I hate agreeing with soapy because 'EverybodyHatesSoapy' meme, but he got me this time. (+1)
