I hope this is not Harald clashing equally with Rocks. We do not need another "Roger level" character .. let top tiers be top tiers.
I mean Greenbull and Fujitora were chilling on random islands before they became Admirals
I feel like Oda's made it pretty clear that top tiers are rare but they aren't that rare. The One Piece world is incredibly vast
Of course you'll see a top tier here and there
