I don't remember where i read it, but i did read about One Piece being about 60% done, apparently there is still enough plot to cover another 10 years (i think it was an interview with one of the editors that works for Oda), even knowing this information is ambiguous i did calculations myself, it's 52 weeks for year so without counting pauses there still is 520 chapters left, and then with that number in mind it made me wonder:
"Are they really gonna stay in Dressrosa for so damn many chapters?, they need to move onto the next islands and make the plot progress past the whole Doflamingo problem"
I agree the fight was dissapointing and too short, but Dressrosa had to end already, it was starting to get tiresome and even felt like the whole Namek saga from Dragon Ball all over again with the constant countdowns, to me the worst part about the Dressrosa arc were those chapters about Luffy and Law running to the top of the hill to fight Doflamingo and Trebol, took way longer than it should and also the dissapoint that Rebecca was, so much potential gone to waste.
Yet i feel they need to move onto other islands and bigger targets as it's not just that i want the plot to progress but i also can't forget what Luffy said in Punk Hazard about defeating the 4 Sea Emperors, and then there are Chinjao's words about Luffy needing to be the strongest of pirates before claiming the One Piece, a tought hit me like lightning:
"What's the point of being king of pirates and having the One Piece if you can't defend neither the title nor the treasure itself?"
(And i'm 90% sure the One Piece is not an actual treasure that can be consumed like gold or jewels)
So i do believe Luffy does indeed need to be the strongest of pirates to properly claim the title, and not just Luffy, the entire crew needs to grow into the strongest one in the seas.
I guess what's left for Dressrosa is the typical celebration that happens at the end of almost every arc and then the good byes, finally to set the next location, i do believe some of the folks in Dressrosa are gonna follow Luffy to his next location.
What i'm hyped the most for is:
News about the Sunny team current status (either captured or still fighting), Luffy's choice for next location (to Zou? to the Wano country? to help the Sunny or to go to the Rebollutionary Army's base with Sabo and the rest to meed Dragon?) and finally...
THE NEW BOUNTIES AND THE WORLD'S REACTION TO THEM.
(I want to see Vivi and Kaya again)
