What mechanism do we have in place to deal with mentors who are bad? Too many people treat it like an achievement (get it and forget it), rather than an in-game duty that has responsibilities and takes some of their time.

As in, people who have the icon, and either play their job poorly, gives out bad advice/wrong information to new players, just doesn't type anything at all, or all of the above?

Case in point: I was in a leveling roulette (The Aery) as tank, with a mentor WHM and 2 first timer dps.
The WHM used nothing but stoneskin and cure 1 all the way to the first boss. The dps ask if there is anything they should know.
I wait for the mentor to respond, about 30 seconds. Nothing.
I go on to explain the fight, then pull. The healer just spams cure 1 until I die, then we wipe. Run back. I ask him to try to keep me in the top half of my health bar. Try again. Same thing.

Do I report the person? Is it even possible for someone to lose their mentor status?
