It's about revealing info to the world, not the viewer. The problem also is, that we only get one chapter like every 1-2 weeks, so it would naturally seem dragged. When compressed into a volume, it might be perceived differently.
Yes.......
VP message is revealing info for the one piece people, but you can't put almost all filler reaction inside the chapter.
Last 2 chap was also mostly reaction, but we also get tons of solid lore info and the situation of Egghead battle slowly moving too.
This chap (so far) has none....
Vivi missing was very old news, literally was published in Newspaper long ago......
The only thing VP info for op world this chapter is the Ancient weapon.....
Roger reaching Laugh tale and finding the op was known throughout the world...
This chap has only 13 page with most of them look like filler too. It's like Oda writing out of force instead of just submitting blank sheet and then taking a break.........
Again, full summary can change something but won't expect much
