I hope sonic makes it out of mid tier next list tbh i think he's better than everyone else in that tier, his most severe matchups are 6/4 and whilst his average is lack luster he as a character can win pretty much every matchup, which isn't true for the vast majority of characters in mid tier.
I hope Sonic AT LEAST switches places with ROB, because ROB is a way way worse character.
ROB after some consideration i think him and DK in the scheme of the game too bad to really be mid tier, mid tier is borderline viable not unviable, and as much as i love using ROB he is a completely garbage character and i'm surprised people still give him credit. Anyone who says ROB performs well i'm sorry but 90% of the American smash scene must be completely and utterly clueless on how to deal with this character, there i said it, i am fed up of this scrub assery existing with this character in your smash scene he is dreadful, if you loose to ROB as: MK,Zamus, Fox or D3, then it is either because the ROB out played you to some ridiculous degree or you didn't know the matchup. To be fair to ROB, IC's and Marth are badly overpolarised, and ROB isn't that common, it's the only possible reason for why this character is performing. Having -4 -3 matchups yeah you know what i'm going there Fox and D3 are -3, and being at a disadvantage to anybody who isn't low tier does not even a mid tier character make.
BTW anyone who says ROB -2s Sonic i'm sorry study this character seriously, ROB is too bad a character, to -2 anybody that isn't Jigglypuff, or -3 anyone who's as bad as Ganondorf.
Also ZSS V ROB is -3 anybody who disagrees hasn't played a Zamus that frame traps every landing you do and foot stool infinite your *** to death lol.
