well you need to kite, make sure they don't get any conditions on you, with that in mind ViM won't work, so kite effectively, don't ball up, a couple of Rangers with Practiced Stance + Seeking arrows staying on a ViM Trapper would ensure they can't get any traps off, you may find the Vim Trappers ball up and try to aggressively trap, the solution is to Nuke 'em good n proper
So remember the key point here:
Conditions on You and Your Party = Their Healing, No Conditions, No Healing, an RC Prot and/or a Martyr would help you out.
