In aoe2 this works because the civs are more or less identical, this would not work in aoe3, if I’m Germans I’ll just ban the two no tp maps, if I’m Dutch I’ll just ban any map that favors aggression, if I’m usa I’ll just try to get maps that are easy to wall, it just wouldn’t work.
However I do like the idea of a map pool that changes every month or so, maybe with one or two of the maps being voted on by the players like this
