Because they will totally not add a new Mario character that was an important NPC in Galaxy and its successor, had minigames in WiiU's biggest Mario game, and has his own game on the WiiU and has a good amount of ballot support?
As for the second, you don't know how many times I wanna slam you.
Dixie has nothing more than her hair, but her hair is so unique.
For Dixie, I'm putting this down here:
http://dixie4smash.wix.com/votedixie#!dlc-highlights/cvsl
It includes my moveset and a general moveset page for Dixie.
Tl;dr
Hair can spin to attack, slow descend, speed up and can allow her to pull off all konds of acrobatic stuff.
Same for Krystal, her staff is what makes her unique,
There is no bo-staff playstyle in Smash yet.
Forget the things about Ice Blasts fans have been telling you, the physical attacks are what makes the staff cool.
They give her a moveset full of mobilty, range and flexibility.
Sorry I'm such a Debbie Downer, I support Daisy, but don't **** on other characters to justify her.
