First off I'm sure there are alot of thread like this, however this is what I'm hoping happens to FF14 in the decades to come.

1. No more war with the Empire, maybe a civil war x-pac, but I'd love to see Gauis offer come true. Cid becomes his right hand man and Gauis becomes Emperor. Then peace happens after the civil war. Why? Well think about it. With the resources of the empire, the tenecity of Gauis, TWO Tias and Crystal Towers? Oh lord. The stuff they could come up with. Which leads to #2

2. The Tia's link so 9th joined Tia travels to, first the Void, then to the other worlds, and eventually to the beginning of it all. Source Tia is the anchor, this way no more soul ripping and the scion can freely travel to different worlds. Now this would mean world syncing but as noone actually lives in the Crystal Tower and Tia said that noone could cause one day it might disappear.

I would LOVE to see a grand cinematic at 6.0 or 5.end where Tia (in his chamber) does a hologram speech thanking all of the people of the first for their hard work, trust and faith, but that now he and the Warrior of Darkness needs to go to another world to help. To go to the Void to restore life there. His hologram turns to that lead guard (sorry cant remember name doing this post before I forget the story I envisioned). And says, "But Im sure your new Exarch will be up to the task." She looks shocked, of course, tries to say no. Tia smiles and just says something epic. They the Warrior of Darkness walk into the hologram beside him, they nod, Tia says a final goodbye and as he slams his staff down a tear rolls down his cheek. The tower disappears and as the tear hits where the ground would be a final gift appears a sandy beach, with crystal clear waters, and the 'ground' in the lake is all crystal.
