Dysfunctional Rules Thread V: Dysfunctions All the Way Down

[Sith_Happens]

Woo new thread!

Recently I realized that, as far as I can tell, troglodytes are only proficient with simple weapons, but their natural weapons are not, as such, simple.

This is related to the Monk proficiency debacle but is not quite the same thing.

I can never remember whether there's a rule anywhere saying that creatures are always proficient with their own natural weapons. If so, then the above is not dysfunctional. If not, then almost everything in the game that has or gives natural weapons has the same problem.

Similar, definite dysfunction: A standard, straight-from-the-Monster-Manual Gnoll uses a battleaxe and a shortbow, but is not proficient with either.
