Completely agree. I keep typing out massive rants but the more I do so, the more upset, angry, disillusioned etc I get. I've followed this series for around maybe 17-18 years at least, I was a lot more casual about it before but took it more seriously after Naruto and Bleach ended and I have to say, after all these years I'm extremely disappointed and fed up with Oda.
It took Jinbei over 10 YEARS to join the crew finally, over 500 chapters! 500 chapters exactly to see Zoro's Asura again too! Oda has been been giving us sprinkles of Shanks and Mihawk at best too after One Piece has been going for what, almost 22 years now at least?
One Piece has really become too much of quantity over quality and becoming too ambitious, over saturated in characters and convoluted anrratively for its own good.
I actually wish Imu and Xebec didn't exist to be honest. At least not with in the current One Piece story but maybe a sequel or presequel series. Or even a "presequel" in the vein of what the Borderlands games did.
