The thing was, people were ignoring the first 2 requirements in voting....does the fic sufficiently follow the prompt and does it include the bonus feature. A lot of times, people weren't including the bonus feature and they were supposed to. Then you have the problem with people voting for or against a fic because of a certain character or pairing.

I agree, when it works, it's a brilliant experience. But there is huge potential problems if every single possible detail is not thought of ahead of time and spelled out specifically.
