So I was under the impression that it was crit>haste>mastery for survival in general.
Yesterday I got http://www.wowhead.com/item=104909 Immerseus neck, it has mastery and haste on it.
Naturally I was thinking to reforge mastery into crit. Then I went on FemaleDwarf, and tried to do a few tests. To my HUGE surprise reforging Haste into Crit on the neck was giving me a nice boost, as opposed to reforging mastery into crit. I tried messing around with reforge, cause I thought maybe mastery was better than haste, but I ended up losing DPS all over the place >.>
So now I am totally confused, why is mastery>haste for this item alone?
For example, I have hit on boots reforged into haste, if I change that reforge to mastery I end up losing DPS.
Maybe someone here has any idea why this is happening?
