"hurr durr why didn't Gaban go to Wano to fight Kaido hurr durr"
Why didn't Kaido leave his fortress with tens of thousands of soldiers to go and challenge Gaban?
How is Gaban supposed to know that Kaido is offering free one on ones?
Is Kaido even doing that? Didn't he use a hag to kill Oden the last time?
Anyone who thinks Kaido is beating Prime Gaban in a fair fight doesn't understand One Piece
