I'm not sure if this is even necessary...
...Because not only has this category remained empty despite Smash 4 having been out for almost a third of a year, but Mii Fighters (along with all other forms of customization) aren't even used in professional tournaments. And even if they are, it's probably only for joke purposes, which we could easily mention on the pages of those respective Smashers, or the article that describes that particular tournament. Thus, of course there aren't going to be any notable players for these characters. I say this category (as well as the ones talking about professionals for the other Mii types) should be deleted.
