3 heal only if the 2 healers REALLY impossible to heal up the raid.
3 heal = less 1 dps, mean need more time to kill the boss and need more healing.
Some MW end up fully fistweaving during raid, IMO, the MW should change to WW spec or use other dps alt to dps the boss. Normal mode DON NEED MW eminence healing at all. If only need 2 heal, y 3?
Use many healers in a fight cannot train good healers. If can solo heal, we should solo heal.
