I do think that there needs to be a certain way that this story progresses. After all, we still need to handle everything in Eorzea first. Heavensward problems aside (like Nidhogg and the soon to be released Void Ark) and then problems that have rolled over from A Realm Reborn (like Omega still in the Flats). Once that's handled we still have Ala Mhigo to worry about since that was technically an Eorzean city state at one point. Once we free them, then I think we should start going to Thavnairian Archepeligo and then to Othard to help free them.
