You are right.
Zoroboys wanted their Grandmaster cutting Dragon Kaido head above the capital -> they got Zoro cutting a Walmart version of it: the magma dragon created by King's sword lmao
Anyways, I still think that Zoro stalling Kizaru would have been better than a boring rematch with Kaku (who should be much weaker than King, and so than Zoro) though.
Zoro vs primary school Mihawk would have been better too.
