I use this in every PvE.
Clansman with void and guard
Warrior Lilith with explosive and paralysis
Prisoner with primordial

When in Lol or BNW I add one of the following depending on the stage.

Desert Marauder with thorn and imunity
Hellraiser with echo and health
Gunner Undead Rescuer with assassin and imunity

Works great everytime.
