Fear kiting is the way to go. The tro jegs have a chance to proc a fire based 250dd on each swing... which if they have a stroke of luck, they can dish out some rather massive damage for being low 40s... Hehe
Pulling them near the ramp is really the best way to fear kite them, as there are no adds on the ramp, and even at the bottom of the ramp, the roamers down there are some distance away, so you can keep fear kiting them still at that point.
