Speaking for myself, I'm fine with the Ancients not getting a happy ending. Despite being huge fans of them, their loss and extinction adds weight to those final clashes in Shadowbringers. As mentioned previously, its a terrible thing that the WoL resolved to do, and the acknowledgment and weight of that is what keeps it effective. There's that, as well as that it adds to Emet-selch's decision to finally pass the torch to the Sundered, and assist you in giving his friend Elidibus his rest, so that he won't suffer on alone. It's painful, but Emet fought and lost, and can no longer lie to himself in saying the Sundered aren't alive, which I think is really bittersweet and wonderful writing.

Elidibus comes to see things similarly, and while I do love the English localization's poetic writing of "The rains have ceased..." in truth, his actual last words in Japanese were rather simple, and included a common Japanese saying of "Shikata ga nai" essentially meaning, "It can't be helped," which I think is also very potent. I took it as him realizing there's nothing they can do to bring the ones they love back, because the Sundered are real living people, just like them, and they can't deny that anymore. So while it hurts, there's nothing to be done about it now.

Sometimes bad things happen to good people for no reason at all, and at the end, came a struggle between two groups of people who simply wanted to save the ones they loved. That Shadowbringers climax instilled in me far more that idea of humanity's willingness to exist than anything in the following expansion—that was entirely dedicated to that predicament. Hence my grievances.

Where my issue arose was that there never was any justice for them. Never, after being clearly affected by the Ancients and their struggle, did the WoL ever question the person who singlehandedly ended them (Got our one dialogue option and a fat load of good that did). I genuinely think Meteion was a scapegoat to avoid this. No matter how noble Venat's intentions were, no matter how deep her guilt, I simply refuse to believe our character would nod and smile at her, a person who has done so much bad and has never answered for any of it. If the WoL opposes Emet-selch despite understanding his reasoning, why is this treatment not given to the even more dubious person? The initial aggressor? I understand not outright attacking her, because she isn't acting against Sundered life, but anything that isn't this mom-mentor nonsense they tried to sell me. I will never understand that...
