The best thing I can recommend is and is the only thing I think most of us have found is:
If you are working with a team, meet in someone's room first, send someone to scope out the lobbies, get in line for one with a pass, and come back and let everyone else know. And they ALL click on same room at once! Don't let ppl not be ready and click fifteen back from everyone.
We did that several times with our teams yesterday and it worked quite well with Pink's teams last night.
It is your best hope! lol 'Cause you know VMK ain't going to get a bigger server today and open more rooms.
Also, about every three games you play I would recommend that the team all take turns getting off the game and reloading it to get back on to help with the crashing!
