I'll play the meta. Roleplayers are largely pack animals. We stick around where we know the rest of us hang out, and Ul'dah was the most popular city in 1.0 because the story was centered there, and blah blah blah reasons.
I think the flipside is that you're more likely to run into jerks in the areas where people are playing "seriously." Mor Dhona's always going to be full of people idling and waiting around for other things to do so the risk of being hassled and trolled rises immensely. Coerthas is arguably the same way; The FATE Train still runs those rails regularly so you're liable to be barged in on seemingly anywhere you end up.
Always better to err on the side of caution, as they say, so I think we're all kept in our locales due to not wanting to stir up the ecosystem.
