Ok I know I am going to get some haters and probably some bad comments back for writing this, but anyone remember the times in vanilla wow when you could practically be anything you wanted to be, not depending on the class/spec,for instance a shaman tank, having your hunter/lock pet tanking, being a smite priest(my favorite), and others.
I was one of the people who got excited when I heard that shamans were getting a taunt, (basically because right now I have the gear for tanking), but now I hear its not for tanking. I have always thought that blizz has more potential to get more out of the current classes. They have a healer class for cloth/mail/leather/and plate...why not think about doing the same thing for tanking? It would just allow more utility and individuality among the classes in my opinion.
