As for my fondness of Pokefiction, to that I can't attest a favoritism. While I love the games and consider them The Source, if someone wants to play true to the manga or anime, I say go for it. Fans with real passion can often find ways to improve their favored properties. I don't believe only the creators have good ideas, we all have a creative process that allows us to define events and circumstances in our own way, and that individuality breeds better stories, and fans can just as easily produce that.
Fiction has no police, it has no jury or execution system, no one should be ruled unfit to write, and that is not anyone's call to make.
