It never sat well with me that Ul'dah received such a disproportionate amount of story focus in comparison to Gridania and Limsa. In particular, a lot of the potential issues with Gridanian society were hand-waved and lessened during the shift from 1.0 to 2.0 whilst much of Ul'dah's problems carried over in full.
At this point, though, I'm more interested in exploring the wider world beyond Eorzea - so 4.2 revolving around the Far East excites me quite a bit.
