At first I thought I wanted int/crit for the mana gain and healing, but with how the current MV heroics and HoF normals are, I'm thinking it might be better to gem int/mastery. I'm at 51% mastery but I think I'm going to try going even higher. (i levae haste out because it's so easy to reach the breakpoint i'm shooting for (3306 as goblin)
Grand Emp shekzeer is pretty rough in the third phase, everyone is usually below 50% aside from the tanks for the entire phase 3.
