Actually this was added because too many Tanks/Healers kept doing the hokey pokey till they got the lvl 50 dungeon they wanted. So DPS who had already waited up to an hour now had to wait another half an hour for someone to just decide to take what the roulette gave them.

It wasn't meant to punish people who had real life things pop up. It was put in to punish the people who were using their quick queue times to get the 'easy' dungeons for their tome grind.

Unfortunately this is why we can't have nice things...and the innocent have to suffer for the guilty.
