I don't speak for everyone, but I'm not too focused on how the characters I want will play, aside from wanting them to not be clones. I support characters mainly because I like them and/or their series, or I recognize their importance. It's supposed to be a crossover; gameplay isn't the most important thing.
In terms of movesets, Opossum's are the only ones that get attention for some reason. Regardless, a fan moveset could very well be far off from what the character's moveset would actually be, so I don't feel like it's the best reason to support a character. I mean, I kind of want Decidueye if he uses trick arrows, but that's an if. Decidueye might just have regular arrows throughout his whole moveset, along with peck and wing attacks.
See, I completely disagree when people say that, “gameplay isn’t the most important thing”. At this point, while there are other factors involved in character selection, I think it’s far more important than it ever has been.
Smash 4 provided us with gameplay additions that we’d not seen in previous titles. Rosalina is a puppeteer, Shulk changes his stats, Robin is a hybrid between magic (distance) and swordplay (close range), Duck Hunt is a 3-part moveset between Duck, Dog, and Zapper, Bowser Jr. fights in a car with numerous contraptions, Little Mac uses a meter, and is very strong on the ground...there’s more I could talk about, but I’ll leave that for now.
My point is, Rosalina wasn’t the most talked about Mario character. That was Toad. Not to say Toad couldn’t be unique, but there was an opportunity to put a different character who provided more on a gameplay level. Very few Nintendo characters provide for a puppeteer moveset, but Rosalina does.
Robin was not considered the front runner for Smash 4. That was Chrom. Robin got in because he had more that made him different from the Fire Emblem roster at the time. If gameplay (or being different) didn’t matter, we probably would have had Chrom.
The focus on gameplay is why, in my humble opinion, Smash 4 has the best roster expansion in the series up to this point. Each character brings something new for the most part.
There’s also the fact that each trailer for Smash 4 focused on gameplay aspects of the character. Robin had a lot of info, and he even makes a point to say, “Which is why I carry my Levin sword!” There's also the fact that it wasn't always necessary to sell fans on the characters. Even in Brawl, we were getting the "All-Star" level characters. Meta Knight, Dedede, Diddy Kong, Wario...all big name Nintendo characters. Now? The characters we're getting certainly don't stack up in notoriety to say, Mario, Pikachu, Link, etc...They can't simply get in on namesake alone. They need something else, and that something else is gameplay.

Speaking of gameplay, I'm fascinated by the idea of Mimikyu. I'm actually going to try catching one and training it for competitive play, but I'm not entirely sold on it making sense in Smash. I've seen it brought up by a number of fans, but I'm not sure how it would translate.
It doesn't have arms to speak of, and i'm not really sure how the Disguise ability would contribute to making it unique beyond a counter of sorts. I'd love to hear some ideas, but again...I'm not sure how it would work in a fighting game like Smash. How does it grab onto the ledges? Would shadow-like arms work? Would that still fit the game?
I'm all ears!
