If you consider "Ignore the entire PHB full of classes and only use the ones in the DMG" to be equivalent to, "A magic doodad doesn't exist in my game" then I think you're the one using the term incorrectly.
And - like I said - this means that the PCs are a cut above the NPCs. I'm not disagreeing that Fighters are better-trained than Warriors in the setting; I'm taking it as a given. (The Heroic vs. Standard array, should you use them, likewise confirms the separation, much like 4d6 rolling and class levels in AD&D.) This is not a bizarre twisting of how 3.x is played or some sort of edge-case. The entire system assumes PCs are predominantly using PC classes.
