Is king not stronger than queen?
Is Kat not the stronger commander?
You’re using the exepctions to make a rule.
I'm using the exceptions to show you that bounty scaling is stupid.
Some bounties are accurate, some aren't.
But I typically wouldn't use them to scale unless there's a lot of evidence to back them up, i.e King being Kaido's RHM, fighting Zoro who's very slightly above Sanji, being named after a card that's equal to Queen's card in most games, etc.
There's no evidence for Vergo > teen Kaido. There can be evidence for PH Law > teen Kaido, but not Vergo. Vergo is just a standard Vet and he likely wouldn't be seen as special to Rocks in any way.
