I wanted Luffy v Shamrock since it'd be cool to see Luffy clash against someone related to his mentor, but Shamrock is a big player so maybe he'll be reserved for later. Would still love for it to be on Elbaph, but Luffy proving himself against Loki like Shanks did sounds amazing.
3 Holy Knights on the island aside from Shamrock, I look forward to more of their personalities, skillsets and match-ups. If the goofy kirin is a Sanji opponent, that'd be great, Sanji needs more aerial opponents. Zoro will get a major fight for sure so maybe that other guy. Maybe some of the Straw Hats can team up against Gunko and we can see Usopp and Nami at their best as support, and maybe Usopp ends up MVP is some way using his observation haki and sniping.
Gaban was great this chapter, pressured Luffy, used a cool and strong attack then gave up when he was impressed with Luffy's form and him having a formidable number 2. Luffy will manage against Loki if it comes to that, and even if Loki has reasonable motivations, I hope it comes to that. Maybe we can get Gaban and Sanji meeting later on, Sanji learning a thing or two from him would be great.
Seems the Recolutionaries' blocking trade routes will be addressed by the government so maybe Shamrock is tasked with that. Teach also showed interest in getting involved so that could be a nice multi-faction conflict (I hope anyways).
