We have the voice lines where it’s told that Tyrande’s fate is sealed and she will die because of her Night Warrior powers, and we have
where Tyrande abandons her people to vengefully disappear in the maw, and how is she going to survive in the maw when she couldn’t even handle Nathanos outside of the maw ?
Just accept it, it’s over for Tyrande. There are several more things that foreshadowed her death and sadly, there’s nothing we can do about it.
