You are going to be very disappointed then but you do you then. Lets agree to disagree.
So are you lol. You guys dont realize that the more endgame villains Oda doesnt resolve (lets say Shamrock, Blackbeard, Akainu, Imu at least), the less time he can dedicate to any of them come the final war/arc right?
Manga chapters are finite. Panel space is finite. Oda releases less pages per chapter and less chapters per year than ever before. Its like him not resolving Kizaru in Egghead and giving him the limelight. Now its heavily likely he gets a few pages to a chapter of conflict before he's resolved by someone else thats not Luffy.
The same point I make about the above characters. The more we spend on NOT resolving villains 90% through the story, the more time Oda has to share with said villains at the end of the story.
So yes, Id much rather have had Shamrock and ~7 HKs be Elbaph's arc presense and lose in 80-100 chapters of focus, to which now he'll absolutely get less of it later on because he has to share with Blackbeard and probably Sakazuki.
