I don't think I have much to disagree with on the current tier list. What I don't like, as silly and insignificant as it may be- The new gaps. I don't really see people like Lucario, DDD and even Toon Link as Mid-tier material.
DDD actually has a solid advantage against important Top tier characters like Marth, Snake, Wario (although he's High tier) and can most likely stand a decent chance against Falco, ZSS and maybe even Pikachu. He's worse MUs that don't give him breathing space are MK, Olimar and ICs, of course.
Toon Link doesn't perform too bad himself, having an advantage over ICs, going even against Diddy Kong and Pikachu, and a decent chance against Falco, Olimar and Marth. His only really bad MU is MK, his only -2.
I don't know too much about Lucario honestly, but going even against ICs, Falco and ZSS may probably be something one would take too lightly.
So yeah, mostly just a peep complaining about labels.
