and they also afk mid-game 90% of the time

I think I've seen one that was, but I haven't seen many in the grand scheme. I think a lot of the good ones get scared off by assholes that can't handle visual evidence of a girl really playing games.

In my experience, the LoL aspect is very true. There have been a few exceptions, but all of the ones I saw who didn't play LoL were playing really out there games, or they had undesirable personalities (either tits, try hards, or people who are too innocent to the point that they don't like swears.)

Yeah. Most of the time there is a girl it's to add a different gender, not add a genuinely interesting personality.
