I normally loathe dailies, finding they make a game feel like work. The crafting dailies, however, have turned out to be an exception. They get me playing alts that I haven't touched in a while; they send me out into the world, where I end up exploring (surveys), and they don't feel too obligatory: I don't feel guilty when I can't do them, but instead, want to do them whenever I can.
Good job, Zen!
