The whole idea of having 3 zones with a city in each zone makes the game world seem tiny even though it's huge.

I would love to see more zones added in -between- the current zones so when you run from city to city you don't just see 2 environments but 3-5.

For limsa maybe have an island where the boat from limsa docks and another boat leaves to thanalan. (and vice versa)

This would make the world feel less structured and thrown together and more expansive and dynamic.

It would also help if these zones had lots of agro mobs making it difficult for jobs under rank 25 or 30 to get through them. It would help to spread the population out as well as create a sense of adventure and discovery when new players begin (ex. they cant just run to every city the first day).
