Well, it's not like battlefield has ever been a historically acclaimed franchise, so I don't mind it because battlefield never really aimed to be that.
It's just an another generic shooter within a popular setting, it's more fantasy than historic documentary.
Not sayin that the female option MUST be there, but it doesn't hinder it in any way either.
People are too quick to jump on the hate SJW's bandwagon without seeing things for what they are, acting in such a way that makes them the same as the opposition they hate.
On the other hand, games like ARMA, which is more of a war simulator than a game, in that setting, it doesn't make sense to add a female option because the game aims for realism above anything else.
