If opposed then make sure 4 or so maps are played before the previous one can be picked again. aka the game selects maps that werent the ones picked over the last 2-3 rotations
Exactly, this was brought up on the first or second page
When a map was played it would be moved to a black list and would stay there for 2-4 rotations. While in the black list, the map would not be selected for voting but after 2-4 rotations that map would be then moved to the green list. 3-4 Maps will be selected at random from the green list and be voted upon for 5-10 minutes before the arena the closes then reopens with the winning map. Maps that are not voted move back into the green list for another chance to be selected and the whole process repeats.
This would ensure that one map will not be played more than once, but however will not take away the popular maps for very long either.
