I thought about posting this in the other thread but that one seems like it had become a bit volatile or at least a fair amount of tension. Is there conclusive data showing that Mastery > Haste or vice versa?
That question stands for both live and on beta. I've been checking up on Requital's, Anaxie and others posts and I am thinking about taking the plunge and changing out my str gems for str/haste as well as reforging to hover around 20% haste and the rest in mastery and would like some advice before doing so. I am not a theorycrafter or familiar with SimC otherwise I would do both tests and see for myself (that and gems are still expensive on my server). Theorycrafting has never been a strong suit of mine.
Keep your strength gems, not worth the hassle when it would hardly bring a change in dps either way. Definitely reforge to haste though. Gear is so heavy in mastery that it is hard to get much, but I currently have 1674 haste rating and it has been serving me very well in both firelands and dragon soul.
