*Spoilers* Anyone feel joining Emet would have been better

As has been posted in here god knows how many times, the "how could she prove" argument is beyond watered down. The echo exists, she can show them that way or they can look into her memories.

I watched the Venat cutscene again on youtube to make sure.

This is what she states about the echo we use to see Hermes and Meteion on that isle: "Process of piecing together an event from ripples left in the ambient aether [...] such memories are giving to fading however and can prove challenging to visit."

So that method could easily not be useable anymore simply because the memories faded away.

That leaves us with the looking into her memory echo. Maybe she even used that to get all those ancients who followed her on her side. But even if she could prove it that way, it would still leave the aspect of how people would react to it.

As we found out in Elpis, the Ancients are not that horrible different from us. They may have a different way to look at the world and their role in it but they still seem to have the same emotions. Even in Eorzea the common people are not told everything because it could lead to panic and more problems. Why should it be different with the Ancients, especially when they on top of having our emotions, have creation magic too?

Its also bad if these things would then reach the attention of the wrong people, including Fandaniel.

So she probably needed to make sure to only show it to people that she can trust AND that will be helpful for the plan. What good would it do to tell x amount of people about the coming doom, hoping that they dont panic or gossip, when they might not have any skills that will help in avoiding it?

Edit:
In the end we dont have all the informations. We dont know if those Ancients we saw in that one recording in shadowbringer were all those that were on her side or only those in the most inner circle..the ones that will die for her. Elidibus only came out of Zodiark because there were enough Ancients against their plan, so I doubt it would just have been those we see in that recording. Maybe she had more on her side that helped but were not willing to bascially became fuel for her.
