I too had this thoughts of how Eorzea, and how small the whole as it's own feels like a hop and skip to places, but just remember, looking at the map, this only one side of the World map, who knows what else they'll bring to the dinner table, people really just need to wait and see, and if you can't do that, un-sub and there's the front door.
Not every MMO-Game can be perfect, I learned this the hard way, I myself do the same thing, I un-sub after I feel like there's nothing more a game can offer until more content is put in place, then I come back and enjoy what it has to offer. Final Fantasy will always have my eye, no matter how low or high the game gets.
