I hope you realise that I'm saying people should vote for who they want on the basis that in all likelihood, there are other people out there who want the same characters you do, therefore, the votes build up.
I'd much rather vote for characters I want, rather than the characters the community thinks make sense. I'm not gonna vote for K. Rool, Shantae, or the Chorus Men, because I don't care about them and they wouldn't excite me at all if they got into Smash (there's also the fact that these characters would be sorely underutilised if they got in anyway - remember what happened to poor old Pac-Man, the character everyone bandwagoned to get into the game because "OMG GUYS HE MAKES SO MUCH SENSE I WANT HIM SO MUCH", yet nobody plays, or even buys the Amiibo of? - but that's a discussion for another time).
I'm gonna vote for the likes of Rayman, Captain Toad, Layton, and hey, maybe I'll throw Dimentio in there. These are all characters I would like to see in the game, and the whole point of a vote is to vote for what YOU want, not what others want.
