I think adding traits to canon characters is perfectly reasonable--it really humanizes them, otherwise, in Bully's case, all we'd be doing is writing about characters getting into random fist fights with each other all over campus xD

I think the issue lies in that the fanfiction community has developed a personal vendetta against characters it deems Mary Sues! Writing should be fun, and of course writing an improved version of yourself--characters that usually end up deemed 'Sues'--is going to be fun! It's like you said, Lucky, critiques should be more constructive rather than vicious.
