This will be an easy fix. Simply put in pvp version of cleric stance. Take White Mage for example, you need cleric stance to use stone, but suffering 80% healing reduction. Cleric stance is either on a 1 min CD or only usable when out of combat. We will see much less healers roaming frontline with false impression that they are good. "You can't kill a healer because you are not good enogu"? Lmao, that is most dumb defense I have ever heard. How are you going to kill 3 healers with 3 dps?
