You should probably post the screen because it's not very visible
Chapter titel: Oden vs Kaido
Expectation: Get at least over 3-6pages of Oden vs Kaido
Reality: Only two pages with one where Kaido take the scar and the other where Oden get defeated....
Cmon when you making a announcement where you literally say that we shouldn´t blink even one single eye, you yet skip most of the fight again... The whole chapter overall sound so rushed, we had already over 9chapters of Oden flashback, one or two more doesn´t would mean much, you can´t such handle the biggest part of the flashback in that way, don´t misunderstand me I can understand why Oda still make these things as offpanel almost 90% of the fights, but it became really frustrating when you see other shonen mangas(Mha,KnY or Black Clover) handle their fight very good but One piece fights almost handle in offscreen...
I know two pages are still fine, but is it really bad to expect more? Oda is better then all this offscreen shit, he can do it much better, the last chapter kinda feel rushed as Oda don´t even plan to do it in that way and end all in one chapter because of the pressure to bring the timeline back to the current version with the strawhats even though he could take more time to make the the raid of Oden and his retainer vs Kaido more exciting.
Now wait for the chapter but if Oden vs Kaido was really only two panels, I would be kinda disappointed...
About the spoilers, the most part doesn´t sound fake though, we see King and Queen, but it should be still clear because the spoiler didn´t mentioned Shinobu after all, so it make sense why people say it was fake.
