The three true problems of Dawntrail are:

1. The playerbase is media illiterate. That is me being nice. The majority cannot read, cannot understand themes that aren't as simple as grief or hope vs nihilism, cannot understand subtlety and require things to be spoonfed to them (but then they get mad about being spoonfed! Get some media literacy then lol!). They are only capable of surface level reading which is why I have to see absolute dumb takes like "Sphene is just Emet-Selch." This leads to the next issue -

2. A lack of curiousity about the other FF games. Seriously, having knowledge on the other FFs actually enriches FFXIV. But for most, XIV is their first FF and most likely their only FF which is a shame. There's no desire to even do simple read ups. I don't think I would have half liked DT if I didn't have prior knowledge of FF9. And this feeds the silly surface level reads I have to see. "Zoraal Ja is just another Zenos", "they're trying to repeat Amaurot". Face. Palm.

3. The Trust system. They haven't figured out how Trusts must work going forward despite having already solved this problem - generic NPCs. As long as they refuse to let the Scions go, we''re likely to run into these awkward scenarios where the Scions are only there for the sake of DF. To be honest? I'm a little sick of the Scions and would not mind having new faces going forward. I wish the writers would not cling to them like this and actually "retire" them. Maybe have some show up again in future expansions, etc, but please let these characters rest. Their developments are done.

DT is not by any means a flawless expansion, no expansion is. I do believe however the problems are overblown and are more player-made.
