I know that it seems weird for Zoro to not have a "real" 1 vs 1 but, as i said many times, this is Zoro's arc. Any other time a strawhat got a lot of focus, and Zoro is going to have even more focus with Orochi, the Shimotsuki and perhaps even Kaido again, Oda didn't give her/him a fight. Never, see Nami in AP, Robin and Usopp in W7/EL, Sanji in WCI.
Zoro did great these last 10 chapters, already had his 1 vs 1 on panel against Kamazo, multiple clashes (Gyukimaru two times, the ninjas, Denjiro) and another moment with Apoo. He is going to do more against Kaido.
But he already went all out and we are already 100 chapters into Wano. The other strawhats have yet to start to fight properly.
If he were to be healed a bit and Oda really wanted to give him a 1 vs 1, the best he could hope for is a 1 vs 1 against Jack. Quite a fast one since he would be quite weakened tho.
I do believe whoever prefers this to a simple 1 vs 1 against King and a great moment at the end of the arc against Kaido is simply mad but they wanted Kaido so badly
