I didn't do a good job of clarifying what I meant. Hbox is obviously the #1 player right now. The question is if he's just totally on another level of every other player, or if we're underestimating puff as a character.
Note that this is a really deep question. There are strong arguments (parry) that in the "20XX" yoshi would be the most viable character right after fox. Given that, is Amsa overrated because he's underperforming how his character should, or underrated since he's overperforimg the "average" Yoshi player?
The system you describe basically just ends up rewarding above average players who use unusual characters. Should Abate be ranked top 20? Probably not, but considering how much he outperforms the "average" luigi (same thing for Amsa, does he deserve to be, say, top 10), he probably would be.
