I had a fun little idea that Square Enix could implement as the game's final 10 or so hours come into the game.
What with these airships flying above the city and all, it is weird that they haven't actually attacked the cities themselves. That is why I suggest as a count down celebration for the version 1.xx's final moments in this world, SE pour waves and waves of Garlean troops into the city. Of course there will a giant problem with not seeing them cause of Ul'dah, so for only those final moments, they allow free travel between city states.
There will be lots of death, it'll be confusing as hell, and maybe, just maybe it'll get people out of Ul'Dah for a couple of hours.
