We will probably never have it perfect. I image in being even harder to draw the line between a "fun" and a "real" map. I see you want to have a place for maps that have style and some nice ideas, but that are just imbalanced for classic 1on1 or 2on2 play. Still, I think a new category for maps like overmind might be good. Maybe we could call it "experimental", maps like soora kingdom would fit in there too.
Would you be the one to look through the map and change it then?^^
