Are women being hidden in real football because they have to play in a seperate league?

Yes. They're relegated to a separate league, where they earn infinitely less money, don't have enough prestige and fame. There's been complaints about that for years and years. Probably from before you were even born.

It's a much easier problem to fix in a game than it is to fix in real life. But when a company tries to change it in the game, there comes the snowflakes to start crying. "I'm being forced to see a woman!"
