For the record, I'm all in favour of women's football being included in the next FM, in fact as a father of two daughters I think it's fantastic
But your argument above makes little sense as all men's leagues have massive bearing on all other men's leagues due to player transfers/nations improving etc. In your example, you may not play in the Asian leagues but I bet players from that region affect the leagues you do play in, whereas the women's league should be a separate database as these players will have zero impact on the men's game and vice versa
