or we could go in the fun-destroying direction of being sceptical and technical and say that for the simple reasons of memory and gameplay, bungie decided they weren't necessary; there were melee units aplenty to fill that spot, and if there were enough melee units, why waste memory and storage space on them?
additionally, having dwarven axemen wouldn't have made sons of myrgard and a long awaited party nearly so challenging or fun. >:D the story just doesn't need them, nor does the game itself.
