Not saying they were done "great", but a lot of this was kind of necessary to really tie everything together.
- Yasu's plot demonizes Orochi and drives home the whole Smile plot, which ties directly to Killer/Kamazo.
- Udon gave Luffy a training arc to hurt Kaido, otherwise people would be massively calling PIS even more than they are if Luffy didn't improve CoA.
- Big Mom being here with Peros ends lingering plot threads from WCI. Problem with that is her crew STILL is a lingering plot thread lol
It was Carrot plot yet she didn't take part in Pero defeat. Wasted plot
BMP being here is one of the worst decisions so far, oda had to keep term away with a bogus excuse by repeating the waterfall fall twice.
Who is Yasu...his story didn't leave a big impact like Pedro so his death is just another random forced plot.
Udon is a waste of ink when only luffu trains vs fodders while Kidd does what? Nothing
The whole plot was boring.
He could have trained with Kidd , both training their haki and even dfs
This arc has so many flaws that only act 1 and chapters outside of Wano are properu executed.
