I think Sanji gets great feats going forward, but beating Queen is not enough for him to push Zoro to medium difficulty.
I'm not confident that Queen can push a bloodlusted Zoro to medium difficulty.
And that was before Zoro awakened COC.
The dynamic where Sanji pushes Zoro to high difficulty and Zoro pushes Luffy to high difficulty as died and there's no indication it's coming back.
If Sanji solos both King and Queen like
@Yasheen and
@Zoro D Goat claim, I'll reconsider, but until then, End of Wano Luffy and Zoro low diff End of Wano Sanji.
Given that, the monster trio feels meaningless. When was the last time Luffy, Zoro and Sanji worked together to defeat an enemy? (The Kraken) Leave Luffy aside, when last did Zoro and Sanji work together to defeat an enemy? (Pacifista on Punk Hazard). When last did they work together to protect Luffy? (Vs Hody's officers on Fishman Island). When last did they save each other in combat or have each other's backs or anything?
For the last 10 years, Zoro, Law and Luffy have been more of a trip or various pairs of duos. Even in this very arc, it was Zoro, Law and Luffy on the Rooftop not Sanji.
Sanji will defeat a Calamity? Yes, I agree. Defeating a Calamity just doesn't cut it anymore when Zoro and Luffy can low diff Calamities.
