Why do you think FI and PH arc were long and boring? First of all, Fishman Island arc was a great and smooth introduction into the New World, bringing the fishmen and the humans one step together, and showing how Hody was so racist even though the humans didn't do anything to him. Secondly, it intoduced a new Ancient Weapon and Poneglyph, revealed that Jinbe is going to join the crew and introduced Big Mom, showing us the humongous power and cruelty of the Yonkou. It also foreshadows that sometime in the future Luffy will fight against Big Mom for Fishman Island to be his turf.

Punk Hazard was the first island the SHs went to in the NW, and I think it did a pretty damn good job. It shows the setting where Aokiji and Akainu fought and reveals some stuff about Vegapunk. It has the SH-H alliance and reveals that Joker is an Underworld boss. It also reveals the K-OA-H alliance and SMILEs.

I wouldn't complain. But I would agree on saying that Dressrosa arc is a better arc than the previous too, but not that they were boring. About the length, I don't know... I thought it was pretty good.
