can i clear up something on tier lists for a second?
tier lists mean nothing in casual play(AKA what the game was designed for). only in competitive play do the mean anything, and even then they are only expectancies of a character's chance to win in a competitive environment, with the characters with higher chances being at the top, and the characters with lower chances being at the bottom.
for example, Meta Knight(the highest tiered character) has at least a +1 matchup on nearly every character in the game, barring only Pikachu and himself, whereas Ganondorf(the lowest tiered character) has no positive matchups at all, with most of them being -4 or -3.
in casual play, however, this doesn't mean anything. my sister, for example, completely destroys me with Ike, a character generally considered pretty bad in competitive play. so don't let your main's tier ranking stop you from using them in casual play.
okay, rant over. =P just wanted to get that off my chest. as far as additions/removals for SSB4, i only really want Mewtwo to come back(either that or add Deoxys). aside from that, i'd like to see tripping get removed, and Sukapon get added as either a playable character or an Assist Trophy(which i hear he was supposed to be in SSBB, but was demoted to a stupid sticker)
