What does "explicitly non-powered" mean to you in the context of a fantasy RPG, where the characters explicitly level up and get "powers"?The hulk is a martial. He is not an explicitly non-powered martial however.
He does not have super strength just because he has a high strength score on the character sheet. The narrative concept is inhumanly powered strength. This is not comparable narratively to literary Conan's strength.
You could do an Earthdawn style game where all classes are powered so Conan the Barbarian becomes magically enhanced at themed things like strength to superhuman levels, but that is a different narrative than heroic non-magical human.
Do you really need the word "magical" or "supernatural" or whatever in front of every ability to be cool with it?
