Not sure if theres a post already, its only a little thing but...
I really do love the little flavour text Blizz gave to Illidan -
'Illidan Stormrage, the first Demon Hunter, betrayed his people by creating a new well of eternity after the demonic invasion of Azeroth. Now Illidan lords over the realm of Outland slaughtering unsuitably prepared Heroes who venture in to his domain.'
Love it
