The least they could have done is give us an adventure somewhere people actually wanted to go to but with how they let the writing bulldoze 90% of the setting in Endwalker all that's left is the thrilling city of lizards who need the scions to go topple their current regime. It's just so bland and uninspired. At this point I would rather they just completely steal 1:1 settings from other FF games like Besaid or Bevelle from FFX instead of what that trailer and keynote proceded to bore me with.
It's not as if there weren't other more relevant places we could have gone to like Corvos which they kept teasing all expansion only to pull this underwhelming surprise. DT is lacking in basically everything from the base plot they described which we know will have to be carried by the same stagnant characters they refuse to get rid of because of fanservice to the generic jungle.jpeg they copypasted into the New World. Thavnair was already soulless, but this looks even worse.
I've lived in tropical countries for a huge chunk of my life and to see them take all the worst aesthetics and aspects of that and make that into an entire expansion we have to sit through for 3 years before the game might actually go somewhere interesting isn't something that sits right with me. If there are people who really want to visit that as an expansion then I can only assume they've never had to deal with stuff like dengue, blackouts, and all the other wonders of the tropics and developing countries I spent most of my life trying to get out of. That weird bit about how the New World was "non-industrial" or something akin to that also struck me as odd pr speech. If the New World in FFXIV had some kind of Spanish or English colonial aspect maybe it would give those of us who aren't crazy about the city built entirely out of sticks something to be midly excited for, but nothing I've seen so far even comes close to lukewarm.
Japan is also leaning towards that more tropical/warm climate from what I understand so I guess from the JP perspective is similar to my own where we look at stuff like the DT jungles and go "this is boring and gross" and then if you show us something akin to Sanbreque or Ishgard we "wow lets go there" because that's what FF as an escape means to us. This isn't it.
