Do daylies, do your roulettes, do treasure maps, sell every item you find to the AH if it is worth something ( I sell things even worth as little as 30g) then npc everything else. I don't go out of my way to make money, and I don't use my crafting either yet somehow I make 100k+ a week. Many high end crafters would even tell you that crafting doesn't make them much profit. That isn't an entirely untrue statement, but it can be difficult to play the market when it is so saturated.
