There should be a 1 min lock out everytime you hit withdraw.

If you aren't ready to hit the queue, You shouldn't be queueing up.

Also this is coming from someone that was doing this to try and hit the queue with my wife and it worked about 40% of the time. But now we don't do anything but High and expert which we can queue together. and trials, which we still hit the same one about 10% of the time.
