To be fair, I think that it's pretty likely that her Void association may lead her to becoming a loot piñata eventually. I do have a soft spot for the Void Elves, too, but it does seem wholly plausible they could go either way.
Besides, Blizzard's killed far more iconic characters than her. Given they've killed Arthas, Varian, and Kil'Jaeden, I think being iconic isn't enough to spare someone the executioner's ax in WoW.

Why are you so obsessed with attractive characters? Do you literally have no other taste for storytelling (even accounting for Blizzard's storytelling being a little sub-par at times) than attractive women? I mean, dude, there's more to life than that, and this seems to be all you talk about. You could carry an Amish boy's Rumspringa all on your own and send him back to his village vowing never to sin again.
