Well...that kind of doesn't bother me since Ty Lee/Azula is my OTP 8D Even if Azula kind of bullies her and is awful and yeah.

That's just your opinion :( I think Zuko, while I like him, is a typical anti-hero. Just like Aang is the archetypical optimist protagonist. And I like both of them that way, so I don't mind Mai being bored and apathetic and cynical and lame teenagery-gothy about everything, because hey, some people really have those personalities.
