Having played a few hours, going in random dungeons, exploring all the nooks and cranies that I've come across thus far... I seem to find enough good quality loot in them, or from vendors. So, how necessary is crafting? Is it only really needed for the harder modes in the game? Because with the "sell v disenchant" dilemma I have when I pick up blues... I'd rather sell them for some gold opposed to d/e'ing them for mats to craft weapons.
