Ability to see the future: Loose plot thread?

[Alleo]

I've heard the theory of Azem having this ability and honestly that would make sense and it would be pretty neat.
What kind of bothers me is the fact the Scions (or anyone, for that matter) could've like asked for Mikoto's aid during the final days or something, her ability would be incredible in times of need, yet no one even thinks about it!

It really depends on other factors: Can Mikoto and other echo users even use it on their own? We for example cant use our echo when we want to. And on top of that we have Mikoto that was like: I keep silent about it because the future should happen as a I see it. And to top it all off, how far away into the future can they see?

That's the other beef I had with it.

The Echo has been firmly established to work by reading the "memory" aether of either souls or the environment, so being able to predict the future is decidedly not something that falls within the scope of what it's previously been shown to be capable of doing and they didn't even bother trying to handwave it by saying it's predicting the flows of aether or some such (Which is how Xenoblade did it).

Well we do have Fordola with the made up echo that is able to have future sights when it was about her attacks. We had to use a device otherwise she just would have known how to stop us because she saw it coming.

I am not against adding to the echo. We have learned with Endwalker that you can see visions in different ways and we know that the echo worked different for people like Minfilia and Kryle too. Yet I am also not a fan of future sight. As in seeing it happening. Having that as being able to predict attacks is okay but Mikotos echo is too much imo.
