I don't think I am to squishy as DRK I have done some big pulls the same as I would do as Paladin and came out none the worse.

You got to use your buffs correctly, in a way where you are constantly mitigating damage and not have to much of a gap till one comes back up.

My biggest problem is remembering to use Scourge :-( Once I hit level 60 I am going to rearrange my skills and hotbars to be optimized.
