So...DRK kinda sucks now.

DRK is way more fun now.
No more Dark Arts spam, effective and interesting mitigation technique in TBN that feels great to pull off.
No other tank has anything as satisfying as TBN right now.

Living Dead is still a problem, but it always has been.
Personally I think the penalty for not getting healed in Living Dead should just be weakness, as if you died and were raised, but without actually dying and losing aggro.

Maybe tweak Abyssal Drain. Reduce it's cooldown, and change it's HP regen calculation to give more for the first target and have it drop off from there.
