If I could have it my way, Id open up the beast Tribe zones in patches, Idyllshire would become a city state, we would start in Gridania, and have to work toward saving Ala Mhigo with the help of the Doman Refugees, Eorzean Alliance, and Ala Mhigans together, and then we'd march toward Othard all in one expansion, eventually liberating it. The Sharlayan island would also somehow come back. Id like the next one to be the opening of new places, and literally double our current explorable areas.
