Rapticor is pretty easy for a named. My 48 druid just cast "Enveloping Roots", "Ensnare", "Drifting Death", "Drones of Doom", and I nuked him repeatedly with Starfire, which did not break the roots.
He never broke the root, never hit me, nothin'.
Root 'n Rot technique is VERY effective on Rapticor, but kiting isn't a good idea considering how many mobs you can't see with all the trees in Wakening Land.
