Eh, the whole point of mirrors is to enable the option of not having to play more than one faction.
not necessarily. People who organize tournaments chose their rules.
If I had to organize a tournament in COH2, and Relic enable mirrors, I would organize it that way :
If BO1 : must be on a symetrical map, each player chose the faction they want to play, mirrors allowed.
IF BO3 : game 1 and 2 played on the same map, not necessarily a symetrical map. mirrors forbidden.
game 1 : player A plays ost, start on north, B plays soviet on south
game 2 : B ost north, A soviet south
If game 3 needed, must be on a symetrical map, mirror allowed, each players chose their prefered faction. No VP bullshit.
That way, all players must learn all the races, but no VP bullshit for decider games.
Even if I'm for mirrors, I think the 'must learn 2 races' has become a COH tournament feature I don't want to lose for COH2. But VP to decide race on last game ?.. I don't like it.
