Agreed, I just think that we went too quick and sudden from more "grounded" matters like Ishgard and Far East to then travelling to a entirely different world (well, not entirely different since it's one of the shards, but you get what I mean) that has almost been consumed and now we have a threat that looms above our heads, that this could happen to Eorzia as well. And then we go to an EVEN BIGGER threat, people turning into monstrosities, anomalies everywhere, literal hellfire pouring down from the sky from invisible source, pretty much a galactic threat to all life and nobody knows why and how it is happening. And we had to time-travel (something that I really, really hate in any media, but it was cool seeing Emet-Selch and other ancients in the past) to even know what the hell is happening and how we can stop it.

To me the last 2 expansions felt more like the endgame, like a final arc of sorts, that was introduced waaaay to quickly. Having the "bigger big bad" each new expansion is inevitable, but they could've paced it a lot better imo, let us explore more of Eorzia first or maybe other shards, slowly introducing the ancients lore and stuff like that, before going full apocalypse scenario.
