Normaly during the molten front daily you have to get to one of the burned defenders and use the questitem to heal them. Yesterday on my priest, was my first time doing the quests with healing spec, I just gave each a hot and I saved them. No more running to them in close range and cast a boring "long" spell when we can finish it from range with an instant. This doesnt work as intended because quests like this usually have to be done with the quest items provided. So it will be fixed in the near future. Have fun while it lasts.
