Cannot start the missions upon recieveing the quest, any information on this issue?
These missions are deceiving at first but basically your going to want to do any of the missions with exclamation points on them. Upon clicking one of these missions types you will see more text showing it has to do with the Firelands. If no exclamation point missions show up do a /reload upon picking the quest up so that the game can fetch new data. There should only be one available at a time. /reload also works after completing a mission so that the next one can be started ASAP.
