I mean not even a proper meeting and interaction between Franky and Vegapunk, or between Robin and the Gorosei.
Yeah it's disgusting, only Luffy is relevant anymore. It's Wano all over again. Though even Luffy wasn't relevant this arc.
There's no reason for why the Straw Hats showed up at Egghead at all. The results would've been the exact same whether they went there or not. Vegapunk died, and his message was sent across the world. It's just been Oda spoonfeeding crumbs of exposition and lore once every three chapters, and the rest has been a total waste of time.
Oda is just lucky he has a very forgiving and already heavily-invested fanbase, because this way of writing does not work at all.
