I pick up every blue amulet and blue ring and cube them if they are junk. My mf barbarian uses a blue 30 res all 35 mf amulet now. I also pick up all of the blue sorc orbs. I'm looking for one with 3 fire skills +3 enchant. I pick up all blue monarchs, and all blue circlets as well. The 25 physical damage reduction mod is very powerful for PVM and is only on the blue stuff. It's the only thing that really protects you from tomb vipers. My amazon uses blue mf boots still.
