I remember threatening my raid group with getting no extra heals if they don't click the effing Lightwell. It didn't take long for it to work.
Healers getting jaded and sarcastic seems completely natural at this point because in every game there is this subset of players that thinks that healers only exist to ensure they can have fun without interruptions and not having to think about pesky things like mechanics, not standing in bad or staying in heal range. Let the healers think about this, let them run after you so you're in heal range, let them heal spam you when they're standing in bad because they've been tunnelling on stabby stab stab again, it's their job, amirite?
That healers are your personal butt wiping machine, babysitter and cheerleader is probably the most common misconception about the role and the one that turns the nicest healer into a jaded pile of salt.
