REPLACE STUFF THAT IS COMPLETELY OUTCLASSED. This is pretty easy. Obviously if someone is using Choice Specs Espeon, you could just say that "Specs Alakazam does this better for reasons X,Y,Z" and be done with it. But it does not end there.
I think that more of a description should be put into this rule, explaining to team raters not to re-build the team for that person. Some raters may look at this rule and think that it is okay to completely change the persons team, when it is certainly not. This needs to be explained more so that it does not end up happening. (It is something that I see commonly.)
