What are the occurences and moments in One Piece where Oda obviously didn't put much effort in his writing of the story or in making the design of a character or a crew ?
I would say that the moments where people such as Pagaya, Pound, Wyper and other characters who should have died of attacks that should have killed them many times without any medical treatment or explanation count.
There is also how he chose Killer's name because he didn't want to do much researches and take time on finding a real-life pirate to name Killer after.
Boa Hancock getting away completely free with her open transgressions against the Marines and the World Government during Impel Down and Marineford arc with her having saved Luffy many times, given him the key to Ace's handcuffs, destroyed several Pacifistas and attacked many marines for no reason surely count too.
And the waterfall scenes with Prometheus being conveniently absent when King attacked the Queen Mama Chanter and Big Mom fell into water, Perospero and other BMP not using their powers to make the Queen Mama Chanter climb the waterfall without the help of the carps and Kaido not going into dragon mode to try stopping the BMP from entering Wano himself, Marco repeating the same thing than King, etc...
Napoleon not saying or doing anything during Big Mom's amnesia. And her getting asleep just before retaliating to Queen's attack on her.
Sabo and Big Mom's amnesias.
The Straw Hats and Supernovas not doing anything to really try to stop Kanjuro from escaping with Momonosuke and them not doing anything against the Beast Pirate ship with long-ranged cannons.
