I mained DRK since SB and quit in the Tower of Babil. I was getting my teeth smashed in even though I all my gear was 530. Back then my healers were fine and I realized my abilities just weren't able to keep up with the incoming damage and how awful oblation is. I switched over to my GNB in exactly the same gear and had no issues. I agree with the points already mentioned but my biggest complaint about DRK has always been their MIT. Why can't oblation just operate like HOC and why can't dark mind be more useful. Their filler combo is boring as hell and I got so tired of it by the tike I hit 85 I never looked back. Unfortunately it sounds like it's even worse now.
