This build involves cranking the damage and utility of your lovely pooch to a point where you basically have a 5th teammate.
The mix of Execution Order and the Kill Order ability modifier for Break The Line results in every Special and Elite enemy dying within a second or two. Mixing Malocator for Execution Order and Targeted Brutality for Break The Line allows you to have maintain higher damage on your mastiff.
The rest of the loadout is meant to facilitate special/elite sniping for your team. The Arbites Shock Maul is just good for everything, and the Bolt Pistol is for it's head popping capabilities. I took Carapace and Maniac damage for the perks because you have so much overkill that you really don't need Flak damage.This is my no means meta, but it's definitely fun to see your cyber-mastiff dealing this much.
