Well when you eventually get to Heavenward you will have PLENTY of those compulsory dungeon type quests. And not only this. I am now stuck on a story quest which seems to have been bugged for basically since the Heaven.... came out. I guess some people somehow got through with complaints, but when I was doing the quest there were about five other players running around also not able to finish the quest ("Crate go boom")
So if you get frustrated now, maybe not bother to buy Heavenward, I am sorry I did. I have easter long weekend and cannot carry on story compulsory quest. GREAT
