It's a drk thing. omg when I enter a dungeon and I see a drk tanking I want to leave, even at 55 where I am now. But I tend to struggle thru.

idk what it is about drks, I hear the abilities are really situational, but about 99% of them I encounter via df take incredible damage, cannot hold hate on more than a couple mobs and are just all around bad.

To make your life a little easier, work on timing so your able to get stoneskin up as the last mob drops so there is no pause between pulls and then get your nocturne shields up on him before he does the next pull, that gives you a little time to get cards running or other things if needed and it allows the tank to get sufficient hate before the cure bombs roll in.

The heals themselves are not bad by any means. Just keep your gear on par and you should be good.
