I'm not big on simulators and doing the math for my dps. I am more of a hit the dummies and live action tests to verify which secondary stats carry more weight. I have been testing haste over mastery since 5.2 and it does seem to up my dps a few percent. Mind you I am single minded Fury with a 500 ilvl. I'd like some input, experience and or numbers other wise. I know for a fact that It's doing more on the target dummy but some times that doesn't translate into Raid boss dps.
