Ah, the picture with the figures.
Honestly, while we are all aware of Sakurai's bias, I think a Figma figure and a Smash character are different concept. While I understand fully the marketing in giving Dark Pit his staff with the Figma, I think it's preferable for Dark Pit to stay as a costume.
While I understand the logic of making Lucina a Marth for beginners, I don't really see reasons to make an alternative moveset from Pit. Also, Pit may not use everything from Uprising, he represent the game well (Palutena and items contribute too).
But, well, that's just me. I'm not a develloper after all.
I think the more versatile characters with different movesets more versatile is Smash Bros 4. Pit and Darkpit are two different characters. It would be a waste if Darkpit is very similiar to Pit. In my opinion its terrible enough that we have to Links ( the same Mastersword, Bombs, Boomerang and so on.. ). Starfox characters shouled be revised too without Fox. But Darkpit could be an unique dark character.^^ It would be a waste if nobody used the potential of Darkpit. Smash Bros could be more versatile with versatile characters. If we would have Darkpit with the same moveset like Pit, a lot of versatile would get lose. ^^
