You're looking for reassurance, and it's there. The class doesn't need to be geared too heavily to start really shining. Once you're in mostly Heroic-level gear (463+) we start doing great. The rotations are a bit clunky when first being stepped into, but once you get it down, they're easy and fluid (especially Inquisition timing, firstname.lastname@example.org).
You've done the hard part in getting to 90, now just gear up a little and reap some of the best time invested.
Someone actually understands the concept of my OP, and replies in a normal calm adult manner.
Actually ret is still trashy at 505.
It gets interesting at 520+ going from 510-530 will increase your damage by 75%. Chances are you won't be doing heroic modes.
