With VIP added the 3 random option map vote is starting to get fairly limiting, skyball will make this more of a problem and if we ever get more King of the Hill maps the chance of even getting to vote for a map you want will be rather small. The simplest option I can see is to separate the vote between mode and map, which order to go for is a question though, both options would leave some cases with no second vote, Canyon Ambush = auto deathmatch, King of the hill = auto Labyrinth/Desert Scrap.
Speaking of which, where is VIP mode for Canyon Ambush?? The permanent spot solves the main problem of the map while still allowing the escort ships to fulfill the ambush part.
