With the Wano arc coming to a end either this upcoming chapter or the next one, it sucks that Oda didn't explore more with Zoro's character.
Don't get me wrong, I do think Zoro had some really good moments like during the fight on the roof or his fight against King and him being revealed to have CoC.
But at the same time it's also really disappointing that Oda didn't focus a lot more on Zoro's character.
Nothing more on his backstory, him not visiting Ryuma's grave(unless it happened off panel), and nothing about his possible connection to the Shimotsuki Family.
Wano arc was the perfect arc to really explore Zoro's character, and give him way more character focus but unfortunately it looks like Oda decided not to do that.
