I knew they would throw Miis in there.
When I saw that they made the villager few m animal crossing a character I thought, "if they are just going to try and fill up the roster with last ass characters like this Miis won't be far behind".
They will only want to put a certain amount of characters in the roster so as not to overwhelm players, so that's why this pisses me off.
They could add Koopa kids, Wart or Mouser (from Mario 2), Mini Kraid or Ridley from Metroid, Ganon monster form, Capitan N (if they own the rights), hell get creative and try and make the dog from Duck Hunt a character. I have a few really fun ideas that I think would be great.
We don't know the full roster yet but I would forfeit villager and Mii for any 2 of the characters I mentioned.
