After seeing an interesting point made in the BiS thread that after capping exp and hit the stat weightings would be str > crit > mastery > hit (27%) > haste, and seeing this same point made a while ago , I decided to run a few experiments to determine the possible difference between stacking hit past the 8% cap or reforging for crit. To do this I conducted a series of 10 tests, of 10 million damage each on the heroic target dummies, once with a high hit build and again with a high crit build.
The spec I used was the
standard fury raiding spec.
During the tests, no sunders were applied and no cooldowns were used. The standard rotation was followed throughout. I have the 2 set T11 bonus. For your benefit, only the averages of all the tests I conducted have been posted. If you wish for more in depth details to be published then by all means ask and I'll post them for you.

As you can see the high crit build is ahead, but only by a small amount. This leads me to believe that given the buffs to Mastery, Raging Blow and Bloodthirst on the PTRs, reforging for crit > mastery over hit both is and will be better for DPS.
