“I am a defender of the faith, a holy warrior and a vassal of my deity. I am not in the party simply to heal your wounds!”
An interesting debate occurred within our gaming group recently. One of our healers, in this case the Cleric, decided that he will not use his Healing Word or any other power that allows others to use healing surges unless a) they are bloodied and b) they have already used their second wind. He is so adamant about following this guideline that he would rather take no minor action instead of healing the other PCs.
