The same can be said for any fictional inspiration when you abstract it, generalize it, and translate it down into a class/level structure. That's how D&D works. D&D wizards are nothing like Merlin. (Heck, they're almost nothing like Turjan of Miir, one of their direct inspirations.) D&D Fighters and Barbarians aren't very much like Conan at all. D&D thieves bear little or no resemblance to Cugel the Clever. Rangers are not much like Aragorn. Clerics are ... clerics from D&D. And so on...IOW, I think the 4E warlord pays lip service to its inspirations, and is only very loosely "based on the true story of" supposed warlords in literature and media. Once you translate a warlord-like character from a book or movie into a 4E warlord, there is so much lost in translation that one hardly resembles the other any more. Or perhaps the translation problem lies in the fact that warlord in literature/media is not really an archetype at all.
