From interview with T17 about WMD as e-sports:
"Maybe we would explore that and maybe we take a leaf out of Team Fortress’ book and have the map symmetrical so everyone gets a fair advantages."
Therefore this suggestion to WA: ability to mirror (one side of a) random map, as to make a map that is identical on both sides.

Could be nice for schemes like elite.. or just to have an easy way of creating a fort-like map out of maps that aren't designed to be.
