Mystery

It's even worse than just "some boring thing", it's mostly the exact same boring thing.
Even if Dynamis existed as some unexplained force in the past, it should've stayed that way. We did not need "the power of emotions" to be literally confirmed.

I would argue that Omega rather did explicitly quantify this. But I can understand the dislike of making a science out of it (even if it's a fringe science in-lore at best). My own feelings for it are conflicted because I personally enjoy speculating on ideas that aren't fully explained, and it can be fun to see how things pan out...or don't. I think we learned a lot of about how Soul Crystals work, for example, in DT's MSQ despite them not being mentioned once. As a lore buff and RPer these open ended ideas can be fun to play with. But then you have a not-insignificant amount of people who essentially need a concept lore stamped on their faces in triplicate or else it's not legitimate, so it's kind of cathartic to see those sorts of people take a solid L when a concept has been blatantly obvious for years.

Not necessarily for those reasons, but I do feel there are definitely time ideas that have been milling around the fringes of the story are explicitly stated at a later date, sadly removing all mysticism, just so the people in the back of the class, so to speak.

Biggest problem is this sentiment is carried over to the game's world aswell. There is absolutely no mystery left in the world of ffxiv, every single thing including the goddamn power of friendship as "dynamis" has been given an explanation. Even the twelve, the gods of the realm have been given a solid no questions left explanation there is not mystique about them anymore. Every single damn thing in this game has a mostly lackluster "scientific" (lore-wise) explanation given to it leaving nothing of intrigue. Nothing is just magic or their own special thing, everything is tied to some boring thing.

That's why I secretly, legit hoped while knowing it would probably never happen that we actually get to another world than Etheyris to start the new arc. We've traveled through space, so in a pure star trek fashion I would have envisioned us landing on another world. Not full of aliens like the dragons the omega or the ea, but perhaps an allagan lost colony that sprouted into a full new world, or whatever.
