As a DRK, even after they fixed double DA, I can still pull 800 DPS (1000-0 TP) on dummy, and in BisEX my fight average is always around 600 DPS. For the carapace phases we have pretty solid burst with our oGCDs and MP dumping with chain DA's. I am usually above at least 1 real DPS class which is nice, but pretty sad if you think about it.
