Agreed on it ending disappointing.
But as for just not liking it because it was "ugly", it's not so much that as you have three zones that are not distinguishable or memorable when compared to other zones, even in the same expansion. There was so much more they could have done with it. Like I said, they could have made the Fringes much more swamp/river valley-esque with Peaks being the rocky/badlands and finally the Lochs being more livable/less barren.
Again, it's just not very distinguishable from Ul'dah.
Fringes (More Green/River):
Lochs (Make the Salt deposits more dramatic, possibly ocean access):
Ishgard was asked for by a large amount of players. This doesn't mean Ala Mhigo won't, but you need a lot more players supporting verbally. By all means, do ask for it! That said, I can't imagine Crystarium not getting housing next due to the unique visuals of the region...assuming there even is a next housing district.
