I personally want mirrors since it makes organising tournaments much easier so we don't have to use the VP leader rule in the deciding matches and even use BO1 for the early rounds.
Now for those guys who don't want mirrors what fairer solutions can you come up with than what we currently have.
How about letting the VP leader choose the map or faction, and then the other player chooses the other item. E.g. the leader chooses Ango (from a pool of allowed maps), then the other player chooses Wehr, so the leader has to play as Allies. Or the leader chooses USA, and the other player chooses Semois and PE.
