This sounds incredibly hypocritical. Nowhere in any rule book does it state that the tank must determine who pulls what. Sure it is beneficial for the group if it is done this way but you have no right to demand anything yourself. People are free to play the game as they like. Just saying, you sound like an entitled tank. Pot calling the kettle black. As a tank it is your job to deal with any given situation, including obnoxious players, or be like that other guy and waste your time by letting people die to prove a point. You are not above the DPS. Also, maybe the WHM didn't have Holy unlocked yet.
