Wow, really good thread you've got here OP. Great analysis, great points, great discussion. I'd just like to hop in and let you know that Parrot Man is not the only one in the company thinking about these issues. I've been concerned about this stuff since I started playing the game post Malz patch and, now that I'm at Riot, am hoping to address some of those concerns. How? By working with artists and animators to make awesome and thematically cohesive champions.
I'm designing a female champ as we speak. I can't say much about her (she's still a long way off) but what I can tell you is that I'm working really hard with the rest of the team to make sure she's totally great and that everything on her "fits", be that looks, gameplay, animations or whatever. She's going to be attractive no doubt, but at the end of the day that attraction factor is going to stem from things that make sense and end up enhancing her character. Is she going to be perfect? Well, I'd like her to be, but I'm sure there's things we've missed that could have been done better. I'm still a rookie and I have a lot to learn. Still, these conversations are being had. We're thinking about gender issues here at Riot. Wish I could say more but you're just going to have to trust me. We've got some amazing women in the (far off) pipeline.
