I hope this is not Harald clashing equally with Rocks. We do not need another "Roger level" character .. let top tiers be top tiers.
Would there really be anything wrong with the King of Giants being a top tier though?

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
