Stuff like... Dynamis, Besieged!, World world and more world.
Dynamis in these 3 citys would be sexy, specially when we get the 3rd floors in LL and Uldah.

Besieged would be insane, like if we had to fight Garlean Raids in Ala Mhigo every so often!!!
We need more world, like the rest of the Eorzea we cant get to yet, then multiply everything by 5 and add the Moon and under the ocean and the mole world undergroud and the tree top village above the black shroud! and and the mountain caves you get lost in!
So much potential...
