While they *may* have actual loot configured that are supposed to drop, the reality is painting a different picture. Most other mobs in the zone drop runes, vendor gear, cards when you farm them over and over in non-quest mode. This one doesn't appear to drop anything. Try it out.
Either the drop rates of the mob are vastly different than other mobs or the drop rate formula for this mob is broken.
I've been holding out on submitting a bug request on a few things in this latest zone (this is one of them) to see if they get addressed in the next patch.
