Even though I had Law > Kid in Wano, things are looking much brighter for Kid.
(1) Law has no CoC so far. His ceiling is set. Kid already has CoC. Zoro insta-unlocked ACoC after getting "basic" CoC. It's just a matter of making basic CoC flow like Ryou. If Yamato/Zoro can do it, Kid will 100% get it.
(2) Law will not beat Blackbeard. That's set in stone. But Shanks is not some final boss for Luffy like Blackbeard is.
(3) And the most important fact: Kid already lost once to Shanks. He lost his arm. Now he already beat a Yonko, and he beat a Yonko with a higher bounty than Shanks. It was 2 v. 1, but he simply has to grow to a place where he can do it solo.
