It IS trolling, no doubt about it. Heka's is the best healing body for almost every job listed on the item. He likely means it "sucks" for WHM, as I know very well his opinion of mage jobs besides WHM. And he'd be wrong even about that. While it is better to cure in Orison Bliaud +2 for the cureskin bonuses, Heka's is still a great precast/idle body for WHM (when matched with a Nefer Khat/+1).
