Blizzard have outdone themselves with tol barad, yes at the moment the ground level is a work in progress and no doubt things are still to be fixed and changed but underground, first glance it looked like bio shock , and it looked very creepy and unlike wow at all. So far i am loving tol barad it truly is a new genre zone in the amazing game . When i firstly herd about it it came across very week with the concept of a prison with dwarfn heritage but now it really has taken a c=grasp on the prison idea and made it extremely dark and i imagine there is a lot of lore behind this place...quite underground evil.
