I would never, ever, EVER want HP sacrifice on a tank, I just don't think it works for a tab-target game. A game like Tera where you can dodge every attack launched at you with pure skill? Sure. A game like this where you eff up and drain just enough HP for an AA after a tankbuster to kill you because it's part of your rotation and you literally can't do anything about being hit by it? Nah.

I think the MP drain was a much more elegant solution to the DRK way of doing things in the context of this game. Sure it'd be nice if they made those MP costs more impactful but I'm glad it's not health. Now HP leeching as a mitigation method on top of their CDs for tankbusters, that I'm all for. Let us self-heal with damn near every weaponskill and then we don't need fluff cooldowns.
