So i was wondering, is there a duel spec option in the game and if not i think it would be a great idea. I would love to go from dps spec to healer spec and change my gear with click of a button. It would be great for every class in the game to be able to go from leveling spec to what ever spec you would need for flashpoints or raids. I dont know what dose everyone else think about this idea.
