Rayleigh hype remains insane. Dude even using age as his reason for not being capable of beating current Teach, same as for Kizaru pre-timeskip. I don't think his speculation makes it concrete that he'd win in his prime but makes it a lot more likely and is great hype regardless. Shakky being a former queen of Amazon Lily's interesting and fits I with Ray training Luffy there and being cool with it.
I loved the Marco/Luffy/Ace stuff, best parts of the chapter. Oda didn't disappoint and I don't mind as long as it comes.
Some would argue Oda's all over the place with his updates but they're just that, updates, Oda always has interesting stuff going on so he's just keeping fans engaged with long-awaited reveals that'll resolve mysteries and build-up to the events to come.
