Use Queue's Humanoid Tagger to tag one of the Di'Zok couriers as they leave Filrek's Eye
A good spot to tag the couriers is at ( 1295, 122, -2164 ) /waypoint 1295, 122, -2164, just on the lip of the canyon opposite to the ramp. Looking down, you can see the couriers. When they approach to the top of the ramp, tag one.
