The lack of spirit on the chest piece makes it the least attractive. Although, it has 3 sockets and you gem for straight spirit, you'll make up for it. Off tier chest has 2 blue sockets and a 120 int bonus. If the tier chest had better stats (mastery/haste) then I would see maybe taking off tier gloves and tier chest. Maybe I'm wrong though :P haven't been able to do much testing.
