Short answer: no.

Long answer: I've been on this site for several years now and the quality of casual hasn't actualy changed. The most you can say has changed is posting speed and frequency of collabs, and even then I'd argue the "old" days are no slouch.

Maybe before guildfall the casual section looked different, but I've never known it as anything other than a mix-and-mash of various different levels of writing skill. Even back when I was more bad than my current level of bad, people in RPs I was in varied from "posts 1 paragraph" to "writes a full novella" all in the same RP.
