I have finally gotten a crafter up past level 20 in tradeskilling (yay carpenters!) and am starting to explore Work and Rush orders for the first time. The main differences I'm noticing is that the Rush orders seem to be half the number of items as Work orders, with what I see as a very short time limit. I'm afraid to take a Rush order because I'm worried I won't have the correct ingredients ready. Is there a pattern to what it assigns you, so that I can prepare ahead of time?
