Alright, there are altogether too many differing opinions on stat priority for destro.
Asmrrobot : Hit > Crit > Haste > Mastery
icyveins : Hit > (Crit = Haste = Mastery)
wowreforge : doesnt look like its been updated lately, but it generally goes Hit > mastery (Crit = haste)
I realize the optimization changes based on GSac or GSup, or aoe vs single target but today I hit a circumstance that seems to make little sense.
I upgraded my weapon last night from the Sha touched staff to a 1h normal ToT sword / 496 ilvl offhand . Heres what ask mr robot shows as my optimized current equipment stats for destruction. (raid buffed)

Now, since ive been tinkering with the idea of going back to affliction to see how well it holds up with my same equipment, just reforged, I flipped the spec choice to affliction, same equipment and had it optimize me.

Now, considering destros mastery, and what i would be trading off by reforging my destruction spec as askmrrobot suggests i should reforge (if i was affliction) I would lose only 4.5% of crit, .96% of haste, and 862 spell power in exchange for gaining almost 30% mastery. Does this sound correct to you? wouldnt 30% mastery be massively better then those? I've been playing a long time and I thought the general formula was 1% crit = 1% more dps. I know CB throws off that calculation a bit, but not by a factor of 6.
Doesnt destro mastery increase damage done by incinerate immolate conflag CB and RoF which basically is everything we do? Why isnt mastery a priority?
