I sympathize with the critique. I thought playing around with z-axis movement, getting knocked up into the air, was pretty cool. The second and third fights are definitely better than the first one.
The only thing I found myself mildly disappointed in was that the path to the final boss seemed almost like a copy & paste of Sohm Al (Hard). Granted, it was a lot more colorful and beautiful. It just seemed a little all too familiar.
Surely this is felt since the Dev team went down from two dungeons per major patch to one. You would think that concentrating on one they'd be able to allocate more resources to it, but- for me personally- I feel that the reason I agree with your point here has to do with that timely decision.I find most of your critique accurate, but I don't agree with the, "dungeons have been bland for 3 expansions straight." commentary. Dungeon quality has been in decline since Stormblood, though.
