All classes have some level of support but usually it's on a very lesser degree for some more than others. Those are the classes I am talking about. Just to make that clear.
But which of those classes would you like to see get a Support Elite Spec next so they also can play the major support role in endgame group content?
For me a Support Warrior elite spec seem very intriguing to me when combo with its core defensive skills I could potentially make an awesome front line healer in WvW that can draw attackers away from my allies. Seem badkittens to me.
