I am normally a tank main so dungeon times have never bothered me. However, I have been trying to level Monk for almost a week now with almost no progress. At least 2 times a day I end up waiting 30+ minutes for a dungeon queue, only to have the tank and/or healer leave the instant we get in.

Seriously, there needs to be a 12 hour lockout for this. If something comes up where you can't join the dungeon, you should just withdraw when it pops. There's no reason to accept it then immediately leave. That just screws everyone out of their queues. There's no reason I should constantly have to queue multiple times (waiting 15-30 minutes each time) just to run a single dungeon.
