I'm actually in the process of writing a big spiel about the state of female players in male-dominated games, but I'll try to summarize my points.
Often, as female gamers, we're cornered (forcibly) into two shitty situations.
A) We hide our gender to avoid harassment / pedestal treatment, thus perpetuating the idea that girls don't play games and as such their needs and desires don't need attention.
B) We are open about our gender and open ourselves up to harassment, claims that we are being attention whores, or being idolized.
The majority of female gamers do not want any of this. We just want to play games we like without our genders being big deals.
I think it's a conversation and solution that has to be met by both genders, because yes, there are girls who could care less about games but play or stream because it's easy attention. But they wouldn't succeed in doing so if guys stopped giving those girls attention.
If you're a serious female gamer and you actually want to stream or cast about a game you love, once again, you are cornered.
A) You are either attractive and get called an attention whore, and your opinions are ultimately dismissed BECAUSE TITS, PLZ STRIP, LOL white knight legion.
B) You are not attractive and people do nothing but call you fat, ugly, still an attention whore and your opinions are ultimately dismissed.
More in relation to league - I have been playing video games and online games for a LONG time. I've never encountered the sort of harassment and harsh treatment in other games as I have within LoL's community.
When we try to voice our opinions about the state of female representation in LoL, we're immediately dismissed as whiny feminist whore bitches who are trying to ruin everything. When in reality, MOST of us are just trying to say "Hey, you know, we're here, we play, and maybe the issue isn't that our population is small so we can be ignored but rather our population is small BECAUSE we are ignored."
Not everybody can have the backbone to stick up for ourselves when LITERALLY THOUSANDS of angry / immature guys are throwing the worst of the worst at us because for whatever reason they think less battle bikinis and strip tease recall animations is encroaching on their rights, or something.
Take this thread from reddit where I told someone off for making fun of chubby cosplayers:

Which leads into my last point - objectifying and sexualizing female game characters has real-world consequences. Every time I see a gorgeous girl post a cosplay pic and either get ripped apart because she is not a size 0, or already skinny girls photoshopping their bodies to hell so that they can look good enough for global acceptance by the male gaze, it breaks my heart.
Having characters who are (at times) obscenely mis-proportioned, or at-best cookie-cutter clones of a busty, thin-waisted, booty-licious diva just reinforces the idea that a female's worth starts with her looks, and not her abilities. These are supposed to be heroes and legends, but very few human females in this game are anything but model - worthy. Nobody is average. Nobody is scrawny and flat-chested. Nobody is a little chubby.
Everybody however has an option to show some T&A, though.
There needs to be a MAJOR mentality swap from current gamers before anything can move forward.
It can start by stopping the treatment of female gamers are evil or goddesses, or whatever. We're just gamers, and we have a right to have concerns about the media we enjoy.
