I'm a bit confused about this as well. Haven't been able to use rawr lately cause of the new changes to armoury (using the rawr3 not the addon) and Simulationcraft. And Simcraft tells me different stat prios every time I regem and reforge according to what it tells me. Today for example I got this:
Int: 3,3568
Hit: 1,8247
Haste: 0,8856
Critt: 0,6456
Mastery: 0,4863
[Edit: only 100 iterations, only self buffed and no BL]
Does this mean I got too much mastery on my gear?
Feel free to have a look and comment on gear/gems/regorge:

Not raiding anything yet, just doing casual runs of za/zg and the random hc:s.
