And only a boring story would have characters become stronger than 99% of the people in the world, and still constantly throw those weaker people in their path 99% of the time.
I was under the impression that the whole reason that Luffy freeing up these former characters of increasing strength on his way down was so that, on his way out, his escape crew would be ordered by strength just like his normal crew, and each character would end up facing a different member of the staff that is the appropriate strength. Just like ever other One Piece arc ever.
Instead, Luffy, Croc, Jin and Iva are obliterating everyone while the other characters are just following behind doing nothing.
