Got it in one. Can't do good melee dps with athe ROG is stuck with an ornate defiant poker
The rest would be your disc rotation and endurance management. I never used the paid class-automations. In ToV I ran a BER and a ROG for hundreds of hours against someone using the BER package though. My BER was within a couple pct dps, some days ahead some days behind. So, essentially the same. The ROG parsed even or better than the BER. Both had comparable raid weapons.
That being said, I think I noticed a change to the endurance regen disc that was my mainstay on the ROG. I haven't messed with my ROG since last expansion. You can look at a previous post of mine for a long drawn-out conversation about how it is important and didn't quite work right with KissAssist. There's a lot of arguing instead problem solving in that thread though, so be warned.
