What's the point with that quite lackluster story in Endwalker?

[SDaemon]

There's no reason to believe they couldn't/wouldn't given knowledge of what happened. (Or at the very least prepare defense)

And yet Emet's own words paint a different picture.

And yet Emet's own words paint a different picture.

Or do they? As this poster pointed out...

Except besides those lines of dialogue, everything else points otherwise. Why wouldn’t they be able to hone their dynamis skills? We know they were able to manipulate it as they use limit breaks in the dungeon. Hermes was able to create a familiar who could interact with it. They had an entire facility again, they could use to hone their skills. They’re commenting on it as how they see it now. Considering they never even got the chance to try, they don’t know for certain. Keep in mind this is the Emet that toiled centuries to being about a rejoining. The rejoining methods would not have brought them that far that is correct. Venat telling them originally what was going on might have. What we know points to them having at least had the right tools, it was a matter of using them. Venat is the one who gambled everything on a single person and had forsaken her own people so i’m not really going to even address her thoughts as she’s the one who kept secrets from them in the first place.
