So I got the PTR up and running this morning, copied over my toon (not a premade), copied over some UI stuff and did a complete reforging following Landsoul's suggested low hit, high crit, high mastery build and then spent some time beating up the Raider's Training Dummy. Here is my report:
Results
My stats as seen in the SS:
Haste - 8.46%
Hit - 8.83%
Crit - 22.64%
Expertise - 25/25
Mastery - 14.49
13.8k DPS over the course of 11.4 million damage.
A few notes of interest:
My priority was CS > BT > RB > Slam > HS (Min 65 rage or battle trance proc)
I didn't use Death Wish or Recklessness at all.
I stood behind the Boss dummy and did not use sunder armor. My spec was 3/3 Deep Wounds and 2/3 Incite.
Rage generation wasn't all that bad. There were 3 times in this test where I didn't have enough rage for a BT or RB. Overall I was very surprised. I definitely pulled more DPS than I do on live, where I usually average somewhere around 12.5k.
This setup looks to be very promising come live.
