Guys, I think I know why specifically Oda had Law and Kid turn out the way they did.
I think a specific reason Oda had Law and Kid’s asses kicked was because of Buggy.
Blackbeard got road poneglyph info after kicking Law’s ass.
Shanks got road poneglyph info after kicking Kid’s ass.
If Blackbeard and Shanks went to Zou and Wano to get Road Poneglyph info, then they likely would have just gotten in Buggy’s way. If Oda really wants to follow through with Buggy’s claim of being Pirate King and Cross Guild ending up going to Zou and Wano, then he prob saw Law and Kid as the excuses he needed to have Blackbeard and Shanks stay out of the way, because now neither of them have any stated reason to go to those places, while Buggy would when he remembers how Roger and Oden got road poneglyph info from Zou and Wano.
