Hello guys, i was talking with my brother about the SoO, but one way or another we ended up talking about Sylvanas..., and there was something that my brother told that is... quite true and now that's bothering me...., How could Sylvanas die with only one shot in the head when she wouldn't die if she jumped from the Icecrown:
Slowly, she crunched her way to the ragged edge of the icy platform. A thousand feet below, shrouded by the clouds, lay a forest of shattered saronite spikes she had scouted out earlier. The fall alone couldn't kill her: her animate flesh was nigh indestructible. But the spikes, the hardened blood of an Old God, they not only would tear the body apart but would obliterate the soul as well.
So how could a shot in the head kill her, if a jump from the top of Icecrown couldn't kill her?!
Here a picture of the icecrown (that's before Arthas became Lich King, so for that time the Citadel didn't exist)
