My guild is going to be working on 25man Heroic Sindragosa this week and im the Tank. I use Frost Resist gear for normal mode but ive heard that on Heroic a tank shouldn't use Frost Resist gear. Is that true? Also I can't seem to find a good strat guide for this. Tankspot only has 10man Heroic and Stratfu doesn't cover Heroic. Any help?
