There really isn’t much going on that warrants long discussions in One Piece. With Wano, it wasn’t active until Onigashima started. We had never seen the Supernova go all out, we only got a taste of Yonko Commanders, never saw Kidd fight, never saw Yonko fight. We had the Tobi Rōppo and cp-0 acting and doing things, etc
We had a lot of new elements to discuss and everyone was taking sides, now it’s kind of predictable. We know how Oda treats top tiers, mid tiers, etc. we can predict pretty well what characters are worth paying attention to and who’s going to be disappointments.
When the story gets very formulaic and the plot trimmed down the cast dramatically, you’re going to get less discussion.
