The sheer amount of city maps that this game has in 3v3 and 4v4s will be for another thread, but regardless what everyone thinks of the current map pool, I think there needs to be more than 2 map bans so that there's at least the option to not have to play on maps we don't like.

Thoughts on this?

You cant ban maps. It is possible to even play on banned maps. 

With the low amount of maps, why would one ban any?

If you cant deal with one type of map, thats your problem
