Hero
A martial character is like Batman or Captain America in the world of D&D superheroes. They are still doing incredible things. They aren't flying. They aren't teleporting. They aren't conjuring things out of nothing.
This is a big point of debate. Its genre confusion. For some people having four color superheroes runs against the genre of heroic fantasy. It would be like having Gandalf in the X Men. Sometimes genre blends can work out great but they usually run better in a universal system that handles both styles. The 4E design shifted the genre focus away from fantasy and more towards supers with fantasy trappings. Some people are happy with the shift and others would prefer that D&D remain a fantasy game at its core and let those who run it decide how much supers stuff to add to the mix.
