I was looking for Rev's Toll today while buying Myth items and I had this lore-nerdy hunch that the place would probably be badly damaged or destroyed in the future.

Think about it: It's the new hidey-hole of the Scions and where most of the adventurers of Eorzea gather. Smart move for an enemy would them to take it out in one fell swoop. In fact, I wouldn't be surprised if the Archbishop sent his troops there on the account of us plotting against Ishgard. (I mean, we did kinda stir up the hornets nest a bit in the storyline).
