Of course it needs to be re-worked with "human" stats, i.e. not 2k Paragon, not +450 stat on each piece, not perfect rolls, etc. But still the farming time to gather the pieces seems reasonable.
And for us multiboxers, Krem's bracers are mandatory for any melee setup, either on equip or on cube.
Also it seems that nobody thought of cubing "The Cloak of the Garwulf" in the cube for DH/Marauder templates. It really fits well with "Zoey's secret" belt, plus simulation shows that it adds non-negligeable dps.
