Apologies if it seemed like I was bashing Shantae, I really, truly wasn't. She is something I would enjoy very much, however, I tend to pessimistic when it's something I want.
Shantae would be very cool and is far from impossible, however, I'm not sure she has great chances either. I think she kinda stands somewhere in the middle, IMO. She does have a little more going for her than SK did, however, they both still retain the same status as indie, which I'm unsure how those stand in Smash after SK's AT. To each their own, though: There really isn't anything that says it can't happen, which I'm glad for. I want her a lot, as she could bring very unique things to the table.
