Sorry to post a new thread in this but I havent been active on the forums for a bit and havent managed to find any thing conclusive on it this, but with the new patch today and MoP just around the corner are the new stat weights i've heard still standing true? Or is this only true with the level 90 talents and totally inconsequential with just 5.0.4?
It can depend on talent choices too, mainly level 90 ones but even with lower tiers haste can actually be better then mastery. The value of haste and mastery now fluctuates depending on your talent choices.
