I am really glad I am a tank. Any dungeon finder in any MMO is always going to have a slow wait time for DPS. No offense, but your the most expendable member of a party. A tank or healer leave or die, your in trouble. DPS goes down, well...you still have one more left. This of course will change with higher end dungeons where you need everyone alive or you lose. Like inSWTOR, if you failed to DPS a boss down in a certain amount of time, they would enrage and everyone would die. Other MMO's have that mechanic as well.
