It does automatically requeue you. I don't know if you go to the front or back of the line (for example, if there are only 5 Feds but 20 Klingons, and one of the Feds is a no-show, do the 5 Klingons who got the aborted queue go to the front of the line or the back behind the other 15?).
I think the mistake now might be that it forces the minimum size instead of forcing a balanced team. No body is bothered by 3v3, but 2v7 sucks.
