Zoro fans bodying themselves
Luffy is the only MC who has gone through proper training and didnt come out mastering all of the techniques. First, future sight. He knew what it is but took his time to master it. After that, CoC. He used it at Marine Ford at such a big stage. Even in Dressrosa. So, learning the adCoC was the next step, and again he took his time to master it.
Zoro is still the most wanked character by Oda.
And as for Law and Kidd.
You need to understand that if Oda gave CoC to Kidd and Law, then people would have complained Oda is spamming CoC powet ups and there is "power creep".
I am glad Oda didnt do it.
As for Zoro, Hakai was the worst thing Oda could do to Zoro (there were better ways to avoid Hakai).
For me, Oda made worst decisions with Zoro, he had to limit himself from over using Zoro. It is still his arc, so he will get back up, but expect nothing major from him now.
Law and Kidd are good example that if you have a good DF, you can still fight against top tiers. And I am happy for that. Additionally, you are forgetting that they are using their awakening.
So, this rant is pointless from my point of view.
However, I agree that Wano is disaster class like
@Pooth said. There is only one thing good and that is Luffy defeating Kaido (I am fine with ZKK after that), and Law and Kidd defeating Big Mom.
