Well, this is a very interesting topic.
I really think that David will develop these aspects further in the game, together with some areas as the underground floor of Lannegar mine, probably to extract bluesteel ingots or the minotaur labyrinth (so big, with stairs not working and no associated quests) just to name a few.
My supposition is that he may need them to save the life of a beloved person maybe...
I am really curious to see what will come ahead, and to see how crafting will be (just creating new items from ingredients or empowering old items too?), yet any quest associated to Botticelli ( what an artist name, lol!) wont' waste him as a money source: travelling varannari are so rare to be really useful to sell wolf pelts at a higher rate, while space is already very limited (and too expensive) to allow players to store even more stuff.
PS: Vo1d, you never learn, don't you?
