Also I think the reason why the big daddies in this DLC have a grappling hook in their drill and the ones in bioshock 1 and 2 didnt is because when they were first realesed into public areas their were problems with their aggresion (This is mentioned in some newspaper quotes from newspapers in the multiplayer).

Obviously having a massive drill that could be shot out of their arm wasnt safe as they would be able to attck anyone who even looked at the little sister. So the easiest solution was to remove the grappling ability to make them less dangerous.
