That is true, but as far as I'm concerned there's a difference between the arcs of One Piece and the arcs of, say, Bleach: One Piece has a lot of islands to visit, so in theory each arc shouldn't go on too long (over 50 chapters, I think) so as not to drag things out unless it's something really important that needs to be covered in a lot of detail.

However, both the Shinobi World War and the Thousand-Year Blood War arcs are very different. They are 1. the final arcs of their respective series, meaning they've got more leeway for going on longer in order to tie up all the loose ends; 2. they're covering large-scale combat with multiple individual fights going on during a war that has over 1000 years of history behind it, necessitating quite a few flashbacks and exposition chapters; and 3. both Kishi and Kubo tend to stretch things out to begin with by drawing lots of large/textless frames on each page - if they condensed and expositioned like Oda did, each arc would be quite a bit shorter.

The Dressrosa arc (and by extension Oda this time around) don't have those excuses.
