I think a character being like, hyper-customizable is definitely a point against them being added to smash. Not a deconfirm but in some cases a point against them. That’s why I think Solaire should get in before chosen undead, dragonborn wouldn’t really make a good fighter, and why a big majority of fans agree elma should be in before the main character of xenoblade x.
With those first two examples (I don’t know if it applies to xenoblade x or not) I think they’re especially true because there’s a lot of variation and customization I’m not just the characters appearence but moves and attacks as well. A character like that couldn’t really represent all possible combinations without being really, really overly complicated
Poor, poor Birdetta...
