@Kolaina, if the tank didn't want to be there, he shouldn't have queued up for the dungeon. If you queue up, you need to do your job, not stand around and whine for a Dismiss the moment you think something has gone wrong.

This tank evidently thought the dps players were bad. The issue was more that the tank had very poor gear--and some slots were empty--so he was probably having issues keeping hate and wanted to blame the dps.

The party wasn't interested in helping the tank to dodge his 30 minute penalty, especially right after the first two pulls of the run. The healer filed a report, and a GM contacted her while the tank was offline, and said that logs would be reviewed and action taken if warranted, etc. When the tank returned--hoping that he'd been kicked already I'm sure--the party did vote to dismiss, and got a new tank almost immediately.

Sorry, but disruptive players need to get what they deserve in situations like that.
