Oddly, I haven't heard much complaining about those not working on the Delera's skeletons (which were one of the few 'how do I damage' mobs in the game). Ghostbane barely touches them on elite, and 'holy' doesn't seem to drop until the mid-teens content. Either a)no one is running Delera's anymore or b)everyone is a caster now or c)players are actually using that holy flame club. I never bought that "new player attrition is because they are confused and frightened by undead" line. But this actually perplexes me.
