About Law and Kid bounties.
Law got the same bounty as Luffy in Dressrosa because they were allies.
Same thing happened here, but Kid got carried because the WG assumed he was an "ally" as well, despite Kid actually desiring to do his own thing and crying about being betrayed by Apoo and Hawkins.
No matter >how< Oda drew their fights, in the end these 3 defeated the Yonko alliance worth 8.99B berries.
So their alliance getting a total of 9B to symbolize that "makes sense".
But about the Yonko title, as people have been saying for quite some time, it's not about pure strength. It's about a political and military influence around the New World. Law and Kid do not have this. Luffy does. Luffy is gonna claim FI as his territory, probably Wano as well, even Zou. He has his GrandFleet and dealt a significant blow to BM's influence inside her main territory, Tottoland.
So it makes perfect sense that Kid and Law, despite getting a good bounty, DO NOT get the Yonko title. This would the actual retarded decision.
About Buggy, Buggy is Buggy. Dude's a force of nature. Dude's been like that ever since Impel Down. Not sure why people are suddenly surprised about it.
