I think Oda did a lot with Zoro in Wano but he didn't complete his character arc which would have taken Zoro to a new level, like pre time skip levels of greatness.
Set up was all there, Zoro had to learn about his family, he had to overcome death on panel, he had to behead Kaido on flower capital, he had to be recognized as second Ryuma and he had to make his own black blade and be the one to make Wano his territory under Luffy.
But that didn't happen simply because if that happened, only for one arc Luffy would be completely outshined. So Zoro's character was compromised in the name of Luffy.
So yes having Luffy take a back seat for an arc or two, would probably make him tolerable again.
Captain part tho I was only joking around lmao tho some Zoro fans seriously believe
@Seth that Nothing Happened was a bad moment for Zoro cuz Zoro was "dick riding" Luffy when virtually people remember Zoro for that moment. He didn't need to do it, he did it out of his Nobility and Highest of Moral compasses.
