I could also flip that around and say that mutants are privileged because they have powers a "basic" human (for lack of a better term) in the MU does not. Works both ways
Doom actually has used foot soldiers in the past that have armor that makes them look like robots. Some of the more advanced Doombots are able to act as Doom in his place. He keeps one of them locked in a dungeon for sentimental reasons because it did it's job so well (Books of Doom) And Zdarsky gave no explanation why Wolverine's senses didn't detect a human presence when he has done so in the past when faced with a high level Doombot and knew it was not the real McCoy.
