so why even tyrande is angry on sylvanas, elune would killed them anyway just to give souls to jailer xd
Her reaction to the "you can't kill hope" line didn't have anything to do with the Shadowlands. It was a spontaneous, petulant reaction that saved no purpose except to utterly humiliate an enemy who dared to defy her with her dying breath and it was rooted in nothing but pure spite. It's basically the same thing Arthas did to Sylvanas hence the flashback in that cinematic.
The absolute state of Warcraft lore in 2021:
Kyrians: We need to keep chucking people into the Maw because it's our job.
Also Kyrians: Why is the Maw growing stronger despite all our efforts?
My problem with it is that you can completely remove the Night Warrior element from the story and not miss it. Like, at all. It had 0 impact on the overall plot and story direction, and had no notable character evolution/resolution. What, she turned Nathanos into a Pez dispenser? Big deal, Nathanos was an absolute nothing of a character that was more of an annoyance than anything.
You know your story is bad when it can be safely ignored and that omission doesn’t impact the other characters/plotlines at all. It’s like WoD, where the plot/story-impact can legit be boiled down into “Gul’dan came back, and then…..” Trash.
