i'll try to not sound how much rude as you sounded to me
giving dark pit is... literally nothing of different from pit is a waste of dpit's potential: now, in switch, dpit could become again a mere alt skin (it would make sense, since I don't think they would put a last minute clone in their initial project -it's a complete nonsense) / completely cut; OR could be declonized (a là luigi: I don't think it would worth the effort); OR could be, again, added during last weeks of development. But it's very likely he won't be a completely new character, with completely different moveset from Smash4's one, and so he will be ever condamned to be a low original character.
Same for Lucina.
The fact is: the thing had sense in melee: the characters were really few, and the entire development lasted too little time to be able to add several other completely new characters.
But now, without counting completely useless addition like dpit and lucina (smash4 versions, I mean!) we still would have about 60 characters. With Smash Switch it's likely we will touch the 70th, ONLY made by completely original characters or at least semiclones (very different from last minute totally copypast clones) if you consider fixing broken hitboxes an insignificant particular, you aren't playing the game: you are looking the css and sweeten your eyes by watching so many Nintendo icons it contains.
But I want to
play the game.
