Let me put it another way then. A Fighter usually comes from humble beginnings and has an innate affinity for the martial arts, a Knight is a noble who has been trained from a young age in those same arts. From a visual perspective both classes are identical. They both use Swords and shields, they both wear armour. and they both use hack and slash animations. Where's the difference from a gameplay perspective? I'm using these because they're the martial analogues to the Sorcerer and Wizard.
