The arc should have focused on Zoro's training, Nico Robin's significance to the overarching story given the history on Wano and the CPO, Kidd's backstory and character development, Kaido and his goals/character/backstory/wanting to die, poneglyphs, and bad-ass samurais with cool designs. The samurai who Yamato was jailed with in her backstory all had cool designs and they only get 2 panels. Why? Because we need more panels of Momonosuke crying? Have we seen ANY cool present-day samurai in Wano yet? I don't think there's been one in a land that's supposedly known for its elite swordsmen. Its fake hype.
Instead much of it has been focused on shitty SMILE designs, shitty Scabbards, lazy Udon "Me gonna break this rock" training, Oden wanking, Otama, asspulling Luffy feats, and Big Meme. We're too deep into OP for that. Focus on the real shit. The story should be far more potent at this point. And then on top of that Kinemon and Kiku are both alive? Let me guess Ashura is alive too huh? Garbage.
Imagine extending the fight between Fukurokuju and whatever that shitty Ninja's name is over prolonging Zoro vs King or Queen vs Sanji. The raid has had plenty of cool action but much of what we should have seen has been shortened because Oda wastes too many panels on useless characters and fodder characters panicking over shit that the reader already knows. I guarantee you we get another 10-15 panels of the Flower Capital and Onigashima fodder panicking for an island that's never going to explode. Now it's like Oda is rushing through shit because he realizes how long the arc has already gone. Now we have to watch Luffy asspull his way to defeating Kaido after beating Katakuri by luck and circumstance and having to use G4 to fight Ulti. It's not good storytelling. There's no reason the Scabbards should be getting more character development than the Straw Hats in an arc that is supposed to be the biggest in OP. Wano is not the worst arc in OP by a long shot but it's certainly been disappointing on multiple levels and the power scaling has been laughable.
The arc is a 6/10 for me so far and that's only because of the rooftop battle, Zoro vs King, Sanji vs Queen, and Nico Robin vs Black Maria. Everything else has been underwhelming and the right stories with the right characters are not being told.
