I'm sure I'm behind the curve in this regard, but we finally pushed a 15+ since they decided to start awarding better gear starting from 12+ and up.
That and the affixes this week are about as good as it gets. Generally speaking we would just push a 10-12 (depending on affixes) and call it a week. Personal choice, just didn't bother for anything over 12+ since gear reward remained same.
Last bit of luck was I got MoS for the 15+ , we finished with a few minutes to spare.
Just curious how many others have gotten this achievement?
Our core group is a Druid Tank, Druid Healer, Ret (me), Spreist, and Ass Rogue.
