I've said this after WCI: "since Oda failed WCI and even the most hardcore fans didn't like it, that means that Wano will ether make or break one piece" and then I said this during Wano "Wano will destroy one piece" and goddammit I was spot on.
I've been hearing from hardcore fans that "during the fights sales will rise up" but contrary to their predictions the opposite occurred. Sales is something that the hardcore fans–who spend their entire time mindlessly debating about power levels and trash talking–cannot understand, these same fans are exactly the ones who pirate the manga and don't even pay for it, so no wander they don't understand sales. People–regardless how much they ones liked one piece–will not spend their money on something that is trash, I mean complete garbage, and that's even to say the least. Wano "objectively" is worse than a fuc*ing Chinese monhoua, that's how bad it is. The hardcore fans will never understand it or accept it, but they're not the ones who pay for it so their opinion on the matter is worthless. The decline in sales will only continue with few ups, but that's it, it will continue to decline...
