Balance Druids brings utility to the raid, casting innervate on healers, using rebirth, increasing spell haste, and applying 13% spell power debuff. For guilds starting in ICC the Typhoon knockback can be a great addition in certain fights like Deathbringer Saurfang pushing the blood beasts and allowing more time to DPS. The big downside of Balance Druids is movement, where they can barely do any damage with the dots and might lose precious seconds of [Eclipse], lowering their DPS.
