Warcraft's elves are pretty subverted. They're more pawns for the higher powers than anything. Their immortality was a tool used to enslave them to protecting the World Tree. The logic being that if you make a race immortal and then make that immortality contingent on the World Tree being alive, they will be highly motivated to protect said World Tree.
Beyond that, they're kinda responsible for a suspiciously large number of bad things that happened in Warcraft history. There are so many examples I will definitely overlook several obvious ones here. Off the top of my head:
* the sundering (thanks, Azshara)
* yogg'saron entering the emerald dream (thanks, Fandral)
* Illidan, nuff said
* The Sunwell - I'm gonna go out on a limb here and call it a net bad thing. It contributed a lot to Arthas's descent into madness/ascent to power and unleashing Kel'Thuzad into the world again was pretty not good.
