Well Miis in general are hated by a lot of idiots who thinks they should have not been in the game. All of the three types of Miis got problems, thanks to this "
beautiful" fanbase we are in.
: UpB too strong, plz nerf.
: Not as good as Brawler, so we'll say it's the second worst character in the game and let this thing die because we don't support any characters except top tiers and old Melee characters.
: Oh, he is the worst, so let's not talk about him, even though this character has good tricks to make itself viable.
People hate Miis because they're new, just like custom moves. Wich shows you how the Melee community influenced other Smash games in a wrong way. Sure, it made the games more popular in the competitive world, but appart from that, I seriously think Melee should stop putting their game into other ones.
Seriously.
