I figured out the daily quests, specially those you need for the achievements such as Tol Barad, Molten Front, Deepholm etc are not resetting unless you are in the zone at 06:00 reset time. Every day you get same quests over and over, not being able to do the achievements you need for specific quests. This need to be fixed. I do not have to stay awake till 06:00 so the quests can change, people have lives, you know
