I'm not against having characters that aren't a part of the "Average student" group, but what I do have a problem with (as I said before), is people who base their stories in a universe with established source material, and either directly contradict or otherwise trivialize that source. I find it disrespectful.

Having a single animagus at Hogwarts. Yeah, that's cool! But, having a group of several animagi, and then trying to use James's group as an excuse to say that it should be fine despite not putting in the effort to write an equally compelling backstory to explain it? That's silly.

Whoah, a Metamorphmagus!? On a deep, well-fleshed out character, with no other absurdly rare wizarding powers only possessed by less than 1% of the total wizarding population? Well, sign me up, that's pretty darn cool! "hey guys can i make a shapeshifter like tonks from the movies. and shes an animagus too who can turn into a dragon :D"? 0/10, not swood enough.

Achieving the incredibly advanced Patronus charm, through a great deal of sweat and tears, over the course of several heavily motivated character arcs? Radical! Randomly possessing this absurdly strong, niche charm, which puts you on a level above even most fully trained Witches and Wizards? Totally not radical!

Do you see my train of thought? Oh, and while I'm making people angry... [hider=Click at your own risk][@RumikoOhara]
I think that a Cerberus Patronus is kind of silly. I don't really see how it fits her character at all. #Shotsfired[/hider]
