People who keep giving Oda excuses after Wano are beyond saving. He is not the perfect Mangaka people try to paint him as, and yes, he does use mystery as a way to keep his series interesting but it's starting to not be anywhere as effective in doing so. These last 2 chapters, if this was in the 2010's when he was viewed at a much higher level, would've possibly broke the net, but due to the massive failure of Wano it's just something the OP community generally knows about.
