Have you not seen how tanking works late game where damage can get really high at times? And you want to use a move where you lose more HP on top of it just for the sake of extra DPS? Think about it. No, give it a serious thought. You want a tank to pump out more DPS by using a skill that eats away at their HP while playing a job where their role is to soak up damage from all enemies while asking a healer to try to heal faster. Now throw this on top of debuffs that screws up a tank's defense and add some potential critical hits and you're going to suffer nothing but wipes just because the tank wanted to put out MAD DEEPS for the sake of beating something 2 minutes quicker. And you can forget about having tanks doing huge pulls in dungeons if this is the sort of move you want in the game.
