I did some work of my own, since this tread got me to thinking.
Gemming mostly for Hit, with a few Str/Hit Purps to get an Str socket Bonus, Forsaking any other type (crit, haste, mastery), Reforging for maximum Hit while maintaining 26 Expertise, and using only Battle Shout and Hit Food and Hit Elixir, netted me with the following:
Str: 4436
AP: 9217
Hit: 27.1%
Exp: 26
Crit: 20.55%
Mastery: 8.57
Haste: 3.4%
I decided to try to Prioritize my rotation as follows: Stack Sunders, CS > HS > BT > RB > Slam with BS Proc during free GCDs. Shout on CD right after a HS. I useing Zerker Rage when I could but didn't worry overly much.
10.8 Million Dmg to Raid Dummy
1: Heroic Strike 27% (39k avg crits)
2: Melee 26.8% (19.8k avg crits)
3: Bloodthirst 19.3% (34.6k avg crits)
4: Raging Blow 12.9% (28.9k avg crits)
5: Deep Wounds (DoT) 5.4%
6: Slam 5.1% (19.8k avg crits)
7: Colossus Smash 3.2% (20k avg crits)
Avg DPS: 13,009
I found I had very little "wait time", and could usually follow every HS with a BT or another attack. Did my best to use DW on CD just after a CS, and Reck right after a CS, with Fury of Angerforge used as often as I could, also right after a CS. The longer the fight went, the higher the dmg climbed until I hit 10 mill done.
Now granted this probably won't matter in a week, if what they say is true and where Mastery and Crit will jump up, but it was definitely interesting to see that hard capping hit and using HS every chance I got seemed, for me anyway, to make a good amount of difference.
Take it for what it's worth.
