Speaking of bosses, unless you are the tank, do not pull the boss - especially if the tank is waiting for TP or CDs to regenerate, or if they are waiting on another player's CDs to restore. Doubly so if it was requested by a party member. Unless it's unreasonable like a fresh restore on Hallowed ground, Living Dead, or something similar. Tanks shouldn't be holding up boss fights in dungeons over that. If you pull the boss ahead of the tank, do not be surprised if the tank and healer run the hell away from the boss room and do not take any actions to help you.
