In all honesty DPS check for Denova is not as strict as most like to think. The proper execution of mechanics is paramount to everything else. Here is a log of a HM 16 Kephess kill. http://dpsmeter.com/knee0knelt (You need to click on the Kephess tab) This group was made up of many alts, fresh 50's, and trials. It was clean and we did not hit any sort of enrage timer. You can see from this our highest DPS was pulling just over 1,400 and we used two tanks and a DPS taunt in the last phase.
The point I am trying to make here is that execution>DPS by a wide margin in the current SWTOR tier. If you can master the mechanics and keep everyone alive you will succeed.
