My main is Warlock and for me it is the best class in the game ^^
I wish we could have Gul`dan or Kanrethad Ebonlocke but I don't think we will see him again :(
I am looking forward for the new class (Demon Hunter) and overhaul of most of the specs and talents which makes the game fresh and appealing to play for more than 10 years. And I want to reap souls with my Warlock
