You'd think that by now everyone would know what they both refer to.Originally Posted by Azrune
Still though, it's obviously Bloodlust for a number of reasons:
1. Horde had Shaman in Vanilla WoW and had Bloodlust before Alliance even ahd Shaman available to them.
2. Heroism was introduced in Burning Crusade. As mentioned in #1, Bloodlust had been around long before that. The name change was just to fit the spell with Draenei.
3. It was called Bloodlust in Warcraft 3 when it was a spell used by Orc Shaman.
I can understand why some Horde get annoyed when they hear Heroism, but by now both sides should really know that there's no difference.
