From a narrative standpoint,
I was disappointed that the events in Ul'dah seemed to just fizzle out. It kind of made the build up seem rather pointless. It wasn't cause it facilitated a major shake up for the Scions and set the tone for the start of HW but it still felt kind of a let down and a rather over elaborate way of doing those things.
Having said that the stuff in Ishgard made up for it pretty well. There was nothing simple of neat about the situation in Ishgard in HW and right and wrong were all not clear cut lines. Plus even though we scored a victory at the end, the repercussions of what we started haven't even begun to rain down on us. 3.1 will start on that as the massive culture shock Ishgard is going to experience will begin to hit home and the chaos such a thing will cause will begin to show. The other obvious issue is the Garleans. They still have access to all that Allagan tech. Who knows what they might be able to pry out of that place.
