Btw, has anyone thought about the luck factor in the mirror matches? Luck being the factor it is (at least in CoH, honestly not really sure about CoH 2), I could see lucky strikes being too dominant in determining the winner, especially in the early game.
Not really, I think better micro and teching with better use of abilities will win games. Mirror matches are less likely to be determined by stuff like faction imbalances and luck has the same effect on mirror matches as a non-mirror match game.
EDIT: Also it actually might be more boring having only 1 matchup in the game, USSR vs Ostheer. We'll be seeing the same matchup over and over again in tournaments because of that. This is what happened in SNF S3, we all know that US vs Wehr is the best matchup but we enjoyed some variety in game play thanks to the OF factions, and tournaments would be less interesting without mirror matches imo.
