There should be a checkbox where you can enable/disable mirror opponents. There is only one ladder and one pool of players. All it does is determine the available opponents, just like in CoH.
what i meant was "rank page" or whatever you want to call it. since you obviously can't compare someone who plays mirror to someone who doesn't. so you would need 2 wehrmacht "ladders", one for non-mirrors, one that includes mirrors. what about someone who plays a few mirror matches every now and then? which ladder would he belong to?
no, doesn't make sense... either include mirror matchups in automatch or don't. no half-assed things.
