I actually made some slight mistakes (Fox above Peach/Yoshi, Link above Chrom) and saw people saying Steve deserved his own tier, which I kind of agree with, and I wás debating it when making the first one. Still think Bayo should be a tier higher, and some other things, but that's not what this is.
Honestly? This is mostly subjective but I don't really like the tiers as they are. IDK, this all just feels a lot better than what the K-means clustering achieved. I still don't think this is at all perfect (Bayo, Cloud, Sora, Junior, Jiggs, Kirby and Mii Swordie especially!) but fixes a lot still, like Roy who honestly should be A+, half of B+ tier being High Tier, Banjo now sitting besides Robin and Ridley, and Belmonts separated from the Little Mac/Ganon Tier.
