I am not talking about granting powers, but things like outright resurrection, the night elves suffered far more during the first legion invasion, than any war afterwards. So why should the night elves be brought back now, when far more more died more horribly and gruesome deaths at the hand of the legion, back in the day.
If blizz has the gal to pull such an godawful storyline, like torching pretty much an entire nation for the lulz, they better be prepared to actually do something with the logical fallout of such a decision, hand-waving it away, with a magical fix it all is not satisfactory in any capacity. It just excuses their piss poor storytellingFrom the Doylist standpoint, the War of Thorns was itself a cheap cop-out so I'm not terribly fussed with having it undone by yet another cop-out, so to speak.
