Revenants as a whole clearly have the best death animation,, with their whole being shatering apart.

Seconded by the death of treants, which is always hilarious. "I have defeated you! Oh wait.... i've been chopped in half.... bugger".

Revenants have a great death animation, unless you suffer from epilepsy =P.

I would place Treant deaths as the number one death animation. I love them looking down at themselves like 'FUUUUUUUUU' before they split in half and die.

Kvaldir's deaths are pretty awesome too.

It suddenly occurs to me that the way in which we delight not only in the mass slaughter of NPCs, but also how we delight in their final moments, highlights how sick we players really are. I am ashamed!

I love that when Sister Svalna in Frostwing Halls spears a resto druid, it's the same animation as dying treants. I like all my tree animations, but the best is when I get chopped in half temporarily. One of many reasons I'm going to miss tree form :'(

I like the Treants a lot, but I think that's a given. If I wanted to pick an animation that doesn't get much recognition, it's one done by the Blighted Corpse (I think) in Sholazar Basin. It's an undead lumbering mob with very large arms -- one of the arms falls off and crawls around him, and then he picks it back up and reattaches it.

I'd have to go with the blood elf male death animation. As much as I hate the entire race, their melodramatic last grasp towards the heavens feels so fitting. Even in death they're flamboyant.
