I don't see why it shouldn't just give you quest failure and put you back where you started if you verify when the Duty Finder comes up. With queue times for DPS being so high, dropping queue means a lot of lost time. More than restarting my job quest. And before the "Play a healer or tank" comes up, my Marauder is actually higher than my Lancer at the moment. I'd rather spend as much time as possible in dungeons instead of chasing FATEs to level it though.

Regardless of the why, it's incredibly frustrating.
