I don't know why people said that it's a downgrade for Zoro to fight King after Kaidou. Like how do you even compare to Sanji vs King got downgraded to Sanji vs Queen
1. Zoro fought Kaidou and Big Mom for 10 chapters
2. Zoro actually hurt Kaidou, left a scar on Kaidou
3. He's gonna fight King after all the rooftop feats. That sounds like an overkill more than a downgrade.
Whearas the whole "Sanji vs King" lasted like 2 panels, Sanji didn't do anything to King, the match up got hyped up by Sanji fans for like half a year, and then Sanji still ended up fighting Queen. Does that sound comparable to the Zoro's situation.?
Adding more to this, Zoro vs King and Zoro vs Kaidou are 2 of the match ups that Zoro fans actually hoped for, and Oda is gonna satisfy us with both match up (potentially)
