Have we considered using a basic set of maps that can be the "next map", with the option that players could vote non of the above? - which would lead to a bigger list of "next" maps - which we then choose from?
i.e. At the end of the match, we either vote to go directly to the next one in line or we vote to look at more options.
I think it is great that the game gives us so much control over what is next, but perhaps we have toooo much. Heck, we can always change the map anyway.
