My vote is for no vote...Rotation all the way!
This way the maps do not have to be neglected -_-
As other people have said, this won't work because of how often the server crashes.
BUT
People are forgetting the randoms that maps attract. When we used to have full map rotations, the server would go dead because of the really crappy maps nobody likes, which is why they aren't voted. Server rotation would be nice, but that'd also means we'd have to remove all the crappy maps so that the server doesn't go dead all the time.
67th way almost always fills up the server.
