I don't see a big disconnect there. Natural language just isn't that precise. If you're proficient in a weapon, for instance, you know how to use it. Someone who is much faster or stronger than you and/or a more experienced fighter who's never even seen the weapon might still be able to beat you down with it, in spite of having no knowledge of it, and could probably do so with a different weapon, an improvised weapon, or his bare hands, too.I don't know about you, but the commonplace meaning of "proficient" does not match with how it is used in 5e. For example, I expect someone who claims to be "proficient" with a human language to be "fluent" in it--there may be rare instances of misunderstanding, but in the vast majority of situations they should be as good with that language as a "native" speaker. "Proficient" in 5e means "you succeed a little more often than someone who has no idea what they're doing, but isn't completely terrible at tasks of that general category (e.g. memory, socialization, fine motor movements/reflexes, etc.)."
Sure, proficiency bonuses and bounded accuracy miss the full range of nuance but they're not entirely outside that range, either.
Natural language is approachable and easy to read. It's also ambiguous and easy to misinterpret.I just find it funny that the commitment to using words as they are used in everyday speech has, in a notable number of places, failed to actually pan out. It's supposed to be simple, to be clear WITHOUT jargon--and it just flat isn't.
