The thing is Shanks GOT a doublespread fighting Kid and 1 shotting him. Its a memorable affair.
Im not talking about Kizaru being weaker than Luffy, Im talking about the event not looking at all impactful. We didnt get a doublespread, nor even true resolution in the same chapter. Oda didnt even let Kizaru actually focus on Luffy.
Again, all of this was me saying that I dont truly believe he's even down, just knocked out while Luffy ran out of gas. There is still potential for an actual fight if Oda can just give us that and not a goose chase.
