Playing Priest, I queued as healer and DPS. Got DPS every time all day (leveling up through Northrend). I didn't really take notice of what I got accepted as in the last dungeon and I just kept playing as Shadow, until I noticed that we were wiping on the first boss and people wondered what I was doing.
I admitted I failed, and I apologized for it, it was a really stupid miss of me, but I was distracted and I didn't pay attention. While leveling, I often just go auto-pilot, watching some series and such to get the boredom away. I get called a retard and other less flattering things.
Then, the tank pulls just as I've barely managed to switch to Holy, so I've got barely any mana when he pulls the ENTIRE ROOM.
He fails to tank all the mobs, so they start attacking just about everyone, me included. I can't keep it up, because I get silenced, I have adds on me and I'm rooted. We ofcourse, wipe again.
And they give me even more shit, but this time I stand up for myself, telling him to stop calling other people things when he fails to do anything right on his own.
Ofcourse, I don't want to stay in a group like that. They were toxic, disrespectful, trolling me and plain dumb. So I leave. I'm not gonna help people like that. And I get a dungeon deserter debuff.
So I get a 30 minute debuff, I get a punishment, for leaving a group that treated me like shit. Where is the sense in that?
This debuff makes no sense. It deters no-one from bad behavior, but it punishes people who haven't done anything wrong. It should be lowered or removed. It makes no sense to keep it. If you don't like people and you don't want to queue with them again, that's easily achieved.
