That's true. But the quest is meant to be a hidden one so it can't be too easy. You refer too the "???"? No it has an actual purpose. I think there should be a new quest at the guild. But only if you have Research Quest 1 and 2 completed and a reputation of 500 at least. The questline has a pretty neat reward but nothing too special or gamebreaking.
True, a very neat idea, probably didn't add some because of time restraints before. Certainly could do that now!
Nah haven't forgotten, just hadn't much time yet, certainly will do that!
