I don't think so. Are you mixing PvP and PvE mods on that piece?
61 Armoring and 66 mod and Enhancement in gloves and legs on my otherwise Conq/Obroan Sorc. In WZ my Willpower is the same as on fleet.
Last night it was 2980-something and today 2800-something. If they "fixed" bolster I wouldn't mind going back to full PvP-gear. But that PvE-set bonus is soooo nice
