Let's play a game: Save the Ancients!

[Yuella]

While this may be true of EW, that does not mean they are beyond saving. If we are arguing the main point of EW story as a justification as to why you cannot save the Ancients, consider that nearly all, if not all, Final Fantasy franchise games have an overarching theme about overcoming impossible challenges and odds in order to defy fate and becoming the person who shapes their own fate. Look at nearly every game and this theme will be manifested somewhere inside of each of the main titles, some more overt than others.

This theme is extremely present in FFXIV and is much more pronounced in later expansions as the feats the WoL and companions accomplish become more and more distinguished to the point you end up saving the Universe as a whole by the end of EW. DT's feats are going to likely be considerably less grand (at least from initial views of it as it isn't out yet) compared to that of EW and ShB, but this overarching plot will likely still exist in some form or another.

With that said, the task of saving the Ancients, based on your words, fulfills the "impossibility" portion of the equation and saving the Ancients in an alternate timeline would be defying fate. From a theme's perspective, I would say saving the Ancients fits in with a classic Final Fantasy styled plot and does have considerable potential down the line to come up in a future expansion .

I can agree with that although I feel they need to experience something similar (doesn't have to lead to a sundering) that make them realize that they need to accept that imperfection exists as a part of society.

I do think we will revisit Azem and their action during the Final Days. The final short story shows Azem running off somewhere in a hurry, maybe they had a plan to save at least some of the Ancients that are not in Amaurot/Elpis.
