Now, here's a question:
If the WoL was unable to effect change in Elpis, how exactly is it they are directly responsible for morbols? And no, I'm not joking. That's a thing you can do while you're there, and the game makes it super apparent their continued existence in the modern world is entirely your fault. There's also the matter of the WoL having say in what traits behemoths have.
The writers make it clear that she at no point divulged what she knew of Meteion or the world's future to her people.
I should also point out Emet-Selch only made it through the sundering intact because she intentionally left a crack in it with full expectation he would recognize it and save himself. This action was deliberately carried out with the intent of facilitating the timeline she'd had described to her by the Warrior of Light. Noting of course she possessed full knowledge of what Emet-Selch and his fellow Ascians would become in time, their objectives, and the untold deaths they would cause in the pursuit of those objectives.
