I did LFD on my level 82 mage and got Vortex Pinnacle. It was a fresh dungeon. As soon as I arrived the others (all from the same guild) said they should have brought X (don't remember the character name). One of them was a lock so I don't know if they were upset that I was a cloth wearer or what. They were all level 84 or 85 (not sure why they wanted to run Vortex Pinnacle). Anyway, someone said no that if X had queued they couldn't have queued for Vortex Pinnacle because they were level 81. Then, I was removed from group. We hadn't engaged a single mob.
OK. I can live with that. The part that was strange to me was that I have the Dungeon Deserter debuff for abandoning a dungeon. Does that usually happen when you get kicked (I don't have a lot of experience with being kicked)?
