Night elves? Really? Okay they have lost things over the years, that comes from living as long as they have, but looking at the draenei or forsaken, they've had it worse, I mean how can you compare the societal shift the nelves have had, compared to having the majority of your race wiped out, hunted across the universe, your home world turned into a corrupted hellhole, or being killed in your homeland, raised as a walking corpse, freed but hated by your own friends and family for something done to you.
When I think tragic races in warcraft, night elves don't even come close.
