I'm so confused right now. I'm at 558 ilvl, have the 4 pc set bonus, and am using a flex bindings. After running countless sims I'm getting haste (11350)>mastery>crit.
For some reason that seems to be a sweet spot for haste for me. That setup is simming at 290474 dps, any other priority and it drops 10-20k dps.
Something else I find interesting is how much lower affliction is siming. In my gear, when I sim affliction at 9778 haste>mastery>>crit my dps drops to 261139.
Here is our log from out clean up raid tonight: http://worldoflogs.com/reports/rt-0t28abx73o8mlii8/
If you look at the blackfuge kill I'm 19k dps behind our affliction lock; he had me by about 10 ilvls for that kill.
