Oct 20th 2010 11:10AM Everyone seems to be giving gastery the pass over. I can say having gone all haste reforging last week vs reforging mastery this week, my boss on boss damage comparison was hands down better with mastery. Mind you I am currently wearing all H-ICC25 gear. I have not tried it in combat spec, but for assassination, there was a night and day improvement in my overall damage and DPS. I think mastery is worth exploring further.
