1. Dressrosa’s did what Wano’s couldn’t and pretty much landed everything allowing the drag before it to be able to be looked over. That’s why it‘s so fondly thought of on rereads, where the pacing really isn’t much of a problem. Fujitora was a boss, the Grand Fleet allowed us to see why the gladiators were so focused on, Kaido’s introduction was outstanding, Doflamingo’s throne speech.
2. Fishman Island‘s ending was brilliant. Jinbei gave Luffy his blood, the children of FI got to begin to break the cycle of hatred that ruined Arlong and Hody, Big Mom’s introduction was creepy as hell
3. PH. Pretty much just a good arc ending. Nothing overly special by OP standards (like all of PH) but it was solid.
4. WCI. The last third of that was a long dragged out mess, Jinbei staying behind was pointless and Sanji needing to be saved by Germa was terrible.
5. Wano. The only good thing was Cross Guild (which didn’t actually happen in Wano), a bit about the Wano lore (which won’t come into play for years) and Shanks was cool (even if it was a blatant Red advert). The rest was abysmal. Rushed through, dropped plotlines, offpanelling, focusing on random crap instead.
