I agree. I have had some runs with terrible troll tanks (one who refused to repair his gear because "it provides more of a challenge"). The way it's setup now is so that 3 or more people can't gang up on a single person and be "mean" to them. However, what it ended up doing was allowing one person to be "mean" to 3, which is much worse. Especially since I notice it is usually tanks that are either bad/trolling, who have instant queues anyway. So when they want to play seriously they can immediately get back into a dungeon. While I, as a dps, have to wait 30-45 min (+15 if I leave the dungeon because I didn't want to waste my time for something I know wont be successful).

A majority vote system would be the ideal solution. Chances are if one person is a jerk,the other two wont vote just to let some random guy get a monopoly on gear. So really the only time you'll see it abused is if it is 3 friends grouped together, which I don't think will happen enough to warrant a real complaint.
