I would not even mind a 100+ chapter arc if there was a shit load of interesting and exciting things happening.
The problem is, there isn't.
Kingdom had an unprecedented 150+ chapter in the Western Zhao Invasion Arc. I do not think Kingdom even has another 100+ chapter arc.
Like Wano, that arc was an arc that was a pivotal moment for the series. Despite the size of the arc, there were rarely any complaints amongst the Kingdom community about it's length.
Why? Simple, the pacing was good and there was loads of awesome shit happening.
Every week, there was something good happening in a chapter whether it be a major or minor character moment, a fight, a reveal, a tactic, a death, there was always something and there were no wasted chapters or characters. Every week, someone did something interesting.
Wano meanwhile? The sheer amount of wasted chapters and unnecessary/bad characters is just mind boggling.
Wano Arc had a decade of build up in advance. Shit could have started quickly.
Arrive in Wano, go to Oden castle, meet Kinemon, get sad Oden backstory, meet other Straw Hats who achieved shit off screen (Zoro rounding up Samurai anyone) and start war.
See how fucking simple that was? Lel.
Instead, Oda has an entire introduction filled with worthless characters like Kiku, Tama, Otoku, Holdem, Urashima that either add nothing or add stupid crap to the story (special mention to Tama the bipedal fodder control plot device).
Or how about we get introduced to a boatload of butt ugly designs for fodder that are completely irrelevant instead of fleshing important characters out like, I don't know, all of the Beast Pirate's most important members?
Even worse is that we have numerous extra characters that add so little but detract from others simply by existing. Like why do we need 9 Scabbards? Four could be removed comfortably and little to nothing actually changes.
One mink Duke (Neko or Inu).
One traitor character (Kanjuro or rewrite a different character).
One Scabbard left behind 20 years ago (Denjiro or Ashura).
One bodyguard sent to future with Momo (Kinemon).
Instead of 9 side characters, we now only have four.
See how simple that was? Lel.
A major rule of writing, if you find yourself actively searching for something for a character to do then that character either needs to never be introduced or needs to be written out of the story.
Also, for all the people that say "Oh but it's weekly, it should be binged read".
I) One Piece is a weekly publication. If it regularly fails to be entertaining on a weekly basis then it's not doing it's job properly.
I have read a weekly 150+ arc chapter on a weekly basis that was entertaining each week. It does not and should not need to be binge read in order to be entertaining otherwise Oda should pull a Record of Ragnarok and publish on a monthly basis if it's really that big of a damn deal.
II) Contrary to popular belief, binge reading shit does not make shit any better at anything and that includes pacing.
I binge read all of Bleach and that series still ranks at my number one spot for most horrificly paced manga that I have ever read. Binge reading did not improve the dog shit pacing.
