I feel if Lucina gets cut, there's a possibility that Robin might as well because they're from the same game (new game comes along, new reps), but I think he's staying mainly because of how original he is (I would love for Lucina to return though; she was able to use spears in Awakening, so I find that could come into her moveset somehow if she was added in. We'll just have to see how her popularity holds out).

And I feel a Mii Mage would be great (I questioned why there wasn't one in this game). Engineer, not exactly so sure; I feel he'd work out more like a Mii Gunner in a sense with a little touch of Snake added in.
