So since premades just came up on PTR, they came with enchanting and JC, so since i'm working out how bad rage generation is (Especially for arms.. ugh), do you think it would be worth it to (hard) cap hit and dodge cap exp, then stack haste with strength/haste in yellow and hit/haste in blue sockets? For fury, I definately noticed a difference, since I could hit heroic strike a lot more often, almost on cooldown even while keeping the normal rotation on cooldown. This is with stacking hit to almost 22% and gemming for haste at the same time.
For arms... eh. The difference isn't that big since you can't stack hit like dual wield can, but the rotation felt a bit more steady, though I was always below 50 rage and never did use heroic strike. This is on target dummies btw.
