Once the fleet was away to Silithus it was clear that it would need time to return to Darkshore and that was exactly what Sylvanas based her plan on. The War of Thorns was effectively lost at that moment.
As for Teldrassil however. No one could have forseen it. Sylvanas either decided on the spot to do it, because of Delaryns taunts or she had the plan all along and shared it not even with Nathanos. We saved as many as we could but there was no way to see this coming and prepare for it. So I just don't see how you can blame anyone but the one who burned the tree down for this.
It achieved nothing. The faction war was dead on arrival, because no side can ever win or loose. I mainly sustain myself with being happy to not be the faction that was for the second time following a psychopathic mass murderer for stupid reasons. There really isn't much else.
I mean Tyrande is actually part of the (Ardenweald) story and is helping her people, I would say she is representing a lot. Much more then the Void Elves, Mecha(gnomes), Worgen and others are. One would think that Alleria would come over to hunt for her sister, but no sign of her.
