Are the new back pieces only able to be upgraded by infusion upgrades only and not normal upgrades? I tried transmuting it to a non-infusion-upgrade-slot back item and I lose the upgrade.
(I wanted to transmute it to a normal exotic magic find back piece with the mf orb upgrade for 7% mf, because these new back armors (and ascended back armors) can only go up to 5% mf)
