[@Viciousmarrow] Illidan is my favourite character in the Warcraft Universe (I suppose the avatar was probably a bit of a give away).

I've been reading through the novel Illidan which blizzard recently brought out, and (without spoiling anything) it clears up a lot of the dodgy stuff about what his motives were in BC and such. You get to see just how misunderstood the Betrayer is and its spectacular.
