If they just added Darkness Dragons to Dragon World, then Darkness Dragons would have access to all of the Dragon World spells. By making them their own world, they can balance them better.

Really, it makes sense that there are good dragons and bad dragons, as well as ancient dragons. It's not quite overkill yet. Once we start getting Space Dragon World and Pirate Dragon World, we've got a problem.
