Its meant to show that all these guys are close with the numbers though, they all are close and you still haven't proven to me how they aren't and I never even ranked Luffy.The part of you post where you said "Snack~Ace, but people say Luffy is above Ace and below Snack!" highlights the flaw of your argument. Yes, they're on the same general level, but that doesn't mean they're close or that Ace can beat Snack. Snack can very well be on the same general level as Ace, and be stronger than Luffy while Luffy is stronger than Ace.
Your attempt to say create these equivalency links fail to prove the point you're trying to make.
You have still yet to prove the flaw in this list because I never said they were all dead equal, I made this list with the opinion that these would be high-Extreme diff fights either way.
