Well they nerfed the staff a bit, but it could still can be an OP dps weapon. It seems more like a "glass cannon" weapon imo. Mage classes won't have anti stun with the staff and mystics would be slowed in bird form with the -45% movement speed. Good for xtals and 70 staff proc would be mostly be needed first.
The only good yellow weapon for DK's seems to be the hammer imo. DK's will be their own counter class with all the -def they can get.
The shields seem kinda OP to me.
The gun and bow look meh. The sword looks alright, not great buy not terrible, with the extra 1k dark damage (not as effective against dark resistance though).
