Dressrosa isn't a large scale battle with many individual fights and a long history that necessitated a whole lot of flashbacks?

While it may not be a thousand years, the events leading up to this arc were enough to get at least a half dozen flashbacks, just off the top of my head. (Law, Doffy, Kyros, Rebecca, Riku, Chinjao ... )
