Story - 5/10
Mixed bag. Has some highs like certain parts of Garlemald, and the 5th zone, but there is too much filler and there is a lot of bad writing and unsatisfactory plot points. Tied with HW as the worst expansion MSQ in terms of plot.
Job Changes - Summoner is more fun to play now but it sucks that your Carbuncle doesn't do anything.
Dungeons - good spectacle on your first time through, but like the rest of FFXIV's dungeons added after ARR, they're not very fun on repeat. No depth or challenge.
Quests - the sidequests continue to suck as usual. Only good sidequests is that blue questline with the au ra girl at the first town in Thavnair.
Haven't touched the new jobs yet.
Art - is okay. The highlights are the boss battles. The new Summoner and Samurai abilities look good. Otherwise, FFXIV still suffers from the same problem going for a higher fidelity look than WoW, which requires more effort to look good, but FFXIV doesn't commit so it looks overall poorer.
Music - okay. I've added a dozen tracks to my favorite's playlist. This expansion has far too many insert pop songs. They're starting to become generic and forgettable, much like how Utawarerumono has dozens of insert pop songs but you don't remember any of them.
