i use 4/40/2 and do just fine in all aspects cept pvp since i dont do 55 pvp
then again i use the set bonus for ravage dmg
i dont pick up deafening defense, pooled hatred, or stagger. since i use a healer companion i dont need the extra dmg reduction, and if im soloing champions for drops. i use a 6/40(extra 15%armor) build since you dont need to immob a champion since your melee hes gonna stay in front of you the whole time anyways. in the 6/40 build i pick up deafening defense to help with the bigger hits champs usually do.
