@Coin People are rarely so plain (or sometimes, even self-aware enough) to just say things like that. They usually phrase it differently. In the case of Imperian, the stated purpose of the new restriction was to make it so there was more "definition" between the three factions (Anti-Magick, Magick, and Demonic), which in turn meant they wanted to pigeonhole classes to factions.
It was literally about precluding zaniness, they just would never have called it that. Whatever term you want to use: zany, interesting, etc, as opposed to bland, cookie cutter, or tame, fact is, it's common for MU* staff to have an inclination to call anything that isn't extremely generic completely "ridiculous."
Is there a degree of interpretation going on here? Absolutely. Is "like omg I can't even rn", or any variation thereof, a valid answer to it? Not even close. Should I feel inclined to take seriously the opinions and interpretations of people who tell me that I can't read, while being unable to read themselves? Absolutely not.
