1: Airships connect all the towns in next to no time.

2: Once quests are all done, what's the point?

3: Teleporting around town with aethyr is faster than walking. (unless you load really slow, like really, really slow! slower than me even! and that's hard to do.)

4: I agree I'd hate to have a world chat unless I could just filter it out of my favored window.

I'm not tryin to contradict you, but the reasons listed to stay in ul'dah are all kinda meh, staying there cuz it happens to be your favorite (say visually perhaps) type city is nothing anyone could say boo to. That's why I hang out in Grid or sit at the Limsa fountain sometimes, I like those places for the scenery. From what I understand 50% of the people in Ul'dah are shout fishing, 40-45% are just totally accustomed to being there and it is now a simple "this is what i do" force of habit situation that they're unwilling to break, and 5-10% want to show off gear.

In the situation we have now, as long as i could filter it, I'd support a "city-shout" just to free the shout fishers that are tied to ul'dah as it stands now.
