What if someone disagrees with the Fan Errata interpretation of a rule? Is that someone wrong on the internet? Does he autolose the argument in the Forum? Are all disagreements made superfluous? This is the "Supreme Court" by another name.

I prefer 5E wasn't written with the vagueness in some areas and lack of rules altogether in others it has, but we're stuck with it until such time there's a hypothetical 5.5E or 6E in the future. We can agree or disagree with people's opinions of a matter, but that's all there is. Consensus does not make it truth.
