I've been working on Challenge modes with guildies lately, we're able to get silvers on most everything in just a couple of attempts, but there are a lot of times where I feel like I just get gibbed by large packs. After watching videos, namely of Blood DKs, they make it look so easy. I was wondering how others have been gearing for them. So far I've just been using my raid gear which is hit capped, exp soft capped, and then crit. Hit and Exp seems like a good idea, but after that is more of where I'm lost. Is more mastery the better idea instead of crit?
