Yo! Been gearing up another lock and I keep running into the same problem. I slightly lower ilvl piece has a ton of mastery on it, but the upgrade does not. Obviously in a perfect world, I won't take a piece without mastery on it. BUT, since I'm trying to gear up for my raid quickly, how much more important is Int than Mastery. Is there some kind of stat weight for them where "X mastery increase" is actually better than "X int increase"? Been looking through a lot of guides and most of the time they just say "Int is our best stat". Any math behind it? Thanks in advance!
