I've died from falling damage multiple times in World of Warcraft.
And I don't mean I was in combat and accidentally ran off a cliff or something, though that's happened once or twice as well.
No, I've jumped off the rises in Shattrath, I've fallen from Dalaran, I've leaped off of Wyrmrest Tower, dismounted above Stormwind (I'm a warlock, I was trying to see if I could save myself by using the teleport they got - It rarely worked as planned), fallen off the Darnassus Tree of Life, and fallen in the lava in Ironforge.
EDIT: Fun anecdote, actually. I was level 80 when I fell in the lava in Ironforge, so I actually had enough health to spend ten minutes assembling a group with fellow guild members, one of whom was another warlock, and have them summon me out of the lava to Dalaran.
