His light blue pets (4) hit at 2100 and have only about 4k hp, best way I have found as ranger to kill this mob is Weaponsheild and burn adds down np before it fades and the normal mob is soloable as ranger melee, Hail of arrows ae rocks em
He comes with or spawns a few adds each being able to hit for almost 2k and they spam dps >.< Without really really fast CC lockdown or a really amazing tank, your group will be smeared across the wall =/
Mobs here also ae root with a 1kdd added to it (I also believe the root is a mini dot).
