Nice guide Evralia. Very cool to already see these compiles and crunch some numbers at this point.
Regarding stats values one point. If:
1% haste = 423 haste rating
1% Crit = 600 crit rating
1% Mastery = 302 mastery rating
With mastery being so cheap shouldn't that placed it above haste on the stat weights? Specially now that all your aff. rotation benefits from it.
