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

[Garet]

Idk how else to explain this to you. You’re acting like they were throwing themselves at Zodiark constantly when this has literally been debunked since base ShB. They did 3 set of sacrifices total. That’s it. Two of those were to save the star. I don’t know how to uncomplicate it anymore than that. They weren’t doing constant sacrifices lol. If Venat had told them the truth beforehand, they might not have even needed to summon Zodiark or sacrifice anyone, so i’m a bit confused on your logic here. Also, how did they give in to despair by summoning Zodiark? He was a solution. One that even we relied upon for thousands upon thousands of years. By that logic we gave into despair by summoning primals to fuel the ship, or ironworks gave in to despair by being willing to sacrifice an entire timeline aka billions of lives. Based on the scene in Anamnesis, their argument wasn’t so much for the sacrifices period as it was the sacrifices wouldn’t stop the final days.

Rewatch this since it is basically a summary of what led to venat's final decision

If you need further and more detailed accounts of what this scene represented. Rewatch all cutscenes from 2.0 till present that involved ascians

If Venat had told them the truth beforehand, they might not have even needed to summon Zodiark or sacrifice anyone.

That is a very big IF lol.
