So some maps get never get played because everyone just alternates between a few maps so my suggestions is that after some time of not being played those few maps will become the only options for a map round or two to increase the diversity of map playing for people who want to go to those other maps. -since everyone votes only dolls, minecraft city v4, b5, and motel.
Those maps are popular for a reason. Making them less played may be a detriment. I know what it is like from the perspective of someone who plays a lot, but new players are more likely to join when Dolls is on the map rotation.
This wont be implimented. The voting system ensures that the server gets to decide which maps they want to play, and if the most popular map gets chosen? Probably means that they are the maps that the server has the most fun playing on.
