Most people didn't want Zoro to be related or have any conections to Wano, that's true
But the problem was that fucking chapter where Oda showed us that Ushimaru and Ryuma look exactly like Zoro, and that Ryuma was also one-eyed
That, together with that Yamato flashback + we finding out about more about Luffy being Joyboy and having the Mythical Zoan Fruit
started to create this expectation that Zoro would have some conection after all, even if most people didn't like it
then, Oda just dropped it
in the end, it left Zoro with these weird things conected to his character that have no pay off
and if Oda isn't going to explore or explain anything else about Zoro in Wano, when is he gonna do it? never again, that's the problem
This is the country of the samurai, the swordsmiths that made all of Zoro's swords, the place 2 great swordsmen look like him and all that shit
If Oda isn't doing that here, then we're never getting anything else anymore, and that's the problem
