What even is armor proficiency?

This.

Training to use armour... it using armour for a day or two until you adjust. Armour proficiency should mostly be tied to stats rather than class. 'Training' in armour is really a bit of a misnomer.

I think I said this earlier, but the physical weaker classes are going to be so burdened by the extra weight, they can't carry the armor anyways. The other possibility is the armor will make them really slow.

Also it might interfere with their magic.
