I found it underwhelming. As hard as it has been advertised, I've been surprised when I hit the end of the quest. I expected more, than a rel. short raid (which's only difficulty is rather the limited camera distance), little (basically entirely from the world detached) story, and a small lore-chest hunt. (btw, isn't there somewhere a completion-counter? Don't know if I've found every box)
I hope there're more quests later, because I find its story has barely begun.
Come on Anogg and Konogg, be quicker to stumble over another threat!
