You do realize that girls play games like CS:GO as well, right?
Some less-so-social people have absolutely distorted ideas about womens' psychology - they're not as different from men as you (want to) believe. I dare to say absolute majority of girls you've potentially played with showed you no sign of these 'girly' psychological attributes that you seem to keen so much on. These "tee hee I'm just a brittle little girl, I want to help people, I don't want to do no harm so I'll play healer, I'd never harm other people so I'll help a specific group of people hurt other group of people"-kind of girls are just a minority, and in a long run they're not the people you actually want to play with... "Ah guys I'm so sorry, I know my heals are not good enough, I just want to help T_T" - no, shut you face, this is a videogame, you're just playing one of the chars that are needed in party to effectively kill other people, if you can't stop fishing for compliments after every fight then reroll to something else, geez.
