Stopppp. You think there is discrimination? Bro, if a team signed a female player, fans would LOVE it and obsess over her.
There are no women because of the demographics. Women of course can reach the same level of skill a man can-- there just aren't as many females as males, which harms their changes.
Not to mention a lot of women that DO play tend to stick to the same tight pool of characters-- there are some that branch out, but they're not nearly as common.
Shy of this, culturally speaking, men are more experienced due to their childhood giving them an early access to the video game scene. In addition to this, it's more socially acceptable and expected for a male to sink time into video games than female-- this may influence the community and it's demographics.
Crying that there are no women is lame. Nobody should care about sex or gender. Care about the teams, their performances and what the players can do. Again, if you think there is discrimination, you're crazy. These teams are dropping serious guap for the most talent-- they wouldn't overlook someone based on their sex.
