Well all 3 aren't limited to one style. All 3 are skilled in melee weapons, thrown weapons, ranged weapons, AND unarmed strikes. Cap ain't a slouch with a gun.
And that's the rub, aint it?
Either the mundane characters get to demand or craft a ton of combat magic items.
OR
The mundane characters get to choose to replicate some of the combat magic items, possibly making them supernatural. A bunch of them.
And? All fighters are proficient with melee, thrown and ranged weapons. Personally I make longbows versatile because I want there to be an option for strength based PCs, but a dex based PC doesn't face any such penalty. But my fix is not supernatural in the slightest.
You don't like fighters, but this post has me scratching my head.
