ok guys....you all need to understand that all classes have their spots in raids and its vital to have all kinds...especially in 25 man raids. Druids have HoTs, shammans can heal well with chain heal and earth shield as well as totems, priests have good aoe heals and big healz, pallies are great at healing single targets eg. tanks, and have great mana efficiency and armor. each class is vital, no one is more important than the other
