I would think having a map 'playlist' like the Shazbot large maps CTF servers, where it just plays you on everything Forgotten and larger, but with a 'cycle map' vote, where you can vote, after a minute or so of playtime, to the next map. There should be some kind of notification system for telling players which map is next, so if everybody hates Mirage, but loves Blade Run, and Blade Run happens to be the next map, then they can vote and be happy.
