So our 10man guild is hitting a road block on Heroic Garrosh. We use a DK and Warrior tank combo. We keep getting him to 12%-20% on the last Empowered Whirling Corruption in phase 3 just before phase 4. When the last set of adds come out the raid falls apart. Can any other class besides a Monk successfully kite the adds? Or any suggestions to get past that?
