I have a personal wishlist in my head that I know will never happen but it's still nice to have hopes so.

7.0 - Ilsabard Expansion dealing with the fall of Garlemald and dissolution of the empire/helping newly independent territories re-establish themself before the power vacuum implodes
8.0 - Return to Eorzea expac, go to several new high-level areas back in mainland Eorzea such as O'Ghomorro, the Coerthan Lowlands, Cape Deadwind, West Shroud etc; mostly helping to deal with Eorzea's own political issue post-war.
