The biggest cause of low dps is death, imo. You hit enrage you mostly have died a lot; rotations at this point aren't that complex compared to HW that you see huge range of DPS from players for most jobs. But the raise penalty combined with time on the floor will kill your output. Two deaths in succession and you are at 50% dmg or so; get multiple dps who hit the floor and thats enrage. 'm not sure DPS checks in general now are as tight and the rotations as hard as in HW, and a lot of the complaining is about optimizing DPS for farm runs, not clears.
