9/14 25 heroic
So currently I'm gemming all 320mastery gems, and only matching socket bonuses of 160int. Fully raid buffed I'm at about 49.50% mastery with like, 8% haste, is the mastery stacking style not viable and/or out of date? There are some fights where I go EF like Dark Shaman and Spoils, but all others I go SS. Most fights we have a monk, a druid, a shaman, and 1-2 priests. Basically I'm just wondering if going the haste build for EF is the best way to go.
