I'm sure MANY people already know this... but get a */Device Blaster to lay trip mines (I have 5 slotted damage/1 slot recharge, and it takes me any where from 6-13 to get rid of them all) on that rock right by the tomb. When the 'herder' is incoming, have the blaster run to the rock directly toward the 'bowl' from the tomb. This puts you outside 100yds, and your mines won't 'splode! When they're all good and stacked, just run toward them... feel the lag, and watch the xp & influence FLY in!
Also, I have a Fire/Dev Blaster... w/ 6 slotted damage Inferno... and if the trip mines don't kill them all (pesky Gorgons), then lay one more Trip mine while the tank is drawing Aggro, then Inferno! BOOM... all gone
ALSO, it helps to have a controller & defender... they can buff the herder up pretty well, and we use Adrenaline Boost and Speed Boost EVERY run!
Well... Happy Herding
