I find drk is fine. Haven't touched gnb yet.

Tons of double weaving and ogcd options. The life steal from soul eater is beautiful, if you add up all the hp your actually taking back through out a boss fight.

I like having to manage my mp to make sure I can use TBN when needed.
Also have to manage my blood to make sure I have 50 blood so I can send out esteem asap.

Thanks to TBN paired with other cd's, I find it really refreshing to see 0 damage from tank busters and unavoidable aoes when the other 3 tanks can't do such a thing. Outside of hallowedground and relying on healers shields.

I think the only thing I don't like so much, but can deal with, is how they handled delirium this expansion.
