Can't change character class to scholar

[Squintina]

Good Morning, and thank you for posting on the Final Fantasy XIV Technical Support Forums.

While this is not a technical issue, we will still be able to assist.

As stated in a previous post, the issue most likely derives from the weapon you are using. You are trying to change jobs but you do not have a compatible weapon equipped. Try equipping something that is compatible with a Scholar (as designated with SCH), then try to change the job. See if it will let you.

Please let us know if this resolves your issue so we can better assist other players with similar problems. We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!

Why can't we get a more accurate error message then? The OP's error message in the game doesn't say anything about weapons, just that the class needs to be ACN, which it is. Wouldn't it be better to have:
To equip "The soul of the Scholar", you must first equip a weapon designated for Scholar.
