I like to think my take on it threads the needle. At least as far as having a complex semi-crunchy Martial goes. And while that Warrior is nearly entirely mundane (its support abilities aren't per say, but they're close enough, and it obviously scales beyond human capability) this is going to be juxtaposed with my take on the Battlemage, which takes the same Battle Combo concept and adapts it for integration with spellcasting, all under the guise of a Summoner type class thats all about conjured weapons and armor.
And meanwhile, things like the Paladin or Monk will have their own power sources and mechanics distinct from magic (Divinity and Psionics respectively), and between all of these and my other Martials (Rangers and Beastmasters as well as the described Rogue and Barbarian in that topic), I'll have the gamut of pokey stabby types from the purely mundane to the basically wizards.
In one story, a wizard conjures an air elemental that picks up a ton of swords and swings them around, basically becoming a mobile Blade Barrier that slices up scores of men before he loses concentration. Conan doesn't fight him personally, as I recall, which is a good reason why he survives.one of these days I would like to see someone go through books and movies and figure out every magic thing that conan every went up against, then suggest instead of upping the martials limiting the casters to that list... how well do you think THAT would go over.
My issue is more with the D&D Core and trying to thread the needle in core, rather than solving it with homebrew
Tl;dr: Make it obvious that martial characters in fantasy settings are still fantasy characters.
