Valo definitely has a large player base of women but how many of them are actually grinding the shit out of the game with the intention(or maybe not even the intention) of going pro? I can't tell you the ratio of men vs women doing this, but it wouldn't surprise me at all if it was literally 1000 to 1 despite valo have a huge female player-base(40% i think?).
This is one of the major reasons men dominate in e-sports. Besides the minor differences in reaction time, the greater tendency of men to throw them self into such competition is what creates such crazy disparity. Realistically, there is no way to address this, there will always be far more men in e-sports but a good start is to make it as easy as possible for women to enter competition. That is what game changers is doing.
And yes, no main circuit team is gonna recruit a gc player just because she's popping off, but a t2 hopeful team might. No one is expecting this to quickly work. It might be futile, but there's nothing wrong with putting in effort to try to elevate the level of play of women.
