Synthoceps. Damage from the Dunemarchers perk is negligible against larger enemies, Synthoceps buffs your melee and super in 3+v1 scenarios. Heart of Inmost Light is better than both for Burning Maul though. Empower procs off of Barricade and then stacked with Roaring Flames your abilities are far more lethal. Then you can just alternate between barricade and hammer throws to keep your empower going alongside Roaring Flames X3.
