As I thought, its just an April Fools thing. Stop crying about it. Nexon isn't sexist or anything so shut up. If nexon made it so you nut shot girls.. that would be fucking stupid. Maybe a cunt shot, but that would be "inappropriate". Parents would throw a shit-fit if they added that, but nut shots are "fine". They only did it so they don't get bitched at by all the stupid parents who suck at parenting and don't try to control what their kids play.
Girls are NOT faster! ITS IN YOUR FUCKING HEAD! Jesus, I'm sick of hearing it. If you believe hard enough that the girls are harder to hit and faster, then thats what its going to seem. Pretend the girl characters are just reskinned males, and you will hit them just fine. I have NO problems killing female characters so neither should you.
