Alternatively, a gamepad speeds things up as well. In my case, using a 360 pad, I just have to mash the A button. 1, 2 - wait - 1, 2 - server full - 1. Rinse and repeat ;)
Been doing this with small breaks for about 3.5 hours now on Diabolos. No luck. Got into queue twice in that time only to get an error a few seconds later.
