On my Wzard all gear bar my belt (which is very good) and gloves (quite good) is from the AH.
However, in the past 3 days I've found almost 20 mil worth of Barbarian gear thats sitting in my stash waiting for my currently lvl35 Barb to hit 60. Literally found amazing pieces for over half the gearslots for him. All werent drops, though. Crafted a pair of bracers worth a good 2-3mil yesterday and a pair of shoulders worth 1-2mil 2 days ago.
Really makes me wonder if theres some kind of secret variable in the game that makes it so that all the good gear you find is for other classes.
