Let's get one thing straight here. I have no problem with people giving female characters a slightly bigger bust. It's when they make their breasts ridiculously huge to the point that if the character was real, she wouldn't be able to walk that I don't like.
What's wrong with loving the character the way she is? Why do you have to mutilate her body? Giving her abnormally huge breasts doesn't make her more attractive.
I guess it's a fetish thing. But really. Huge breasts are overrated. Are we still in the 90s?
