Okay... So given that the King Chad Mondstadter is fucking around in Nod Krai, they should totally add a port island (or something like that) to the east next, as having having corridor to Nod Krai only from Natlan is retarded for various reasons.
Also as others have mentioned previously, it would make a lot more sense to have Nod Krai be positioned north of Mondstadt in the first place.
tldr: wtf, dawei
