I've tried this build out in Auric Maelstrom and it works well for me in Auric Maelstrom. Just be vigilant with the special spawns. Honestly, This is kind of a meme build just for the fanning pistol. The idea is to squeeze out as much damage as you can from fanning hence all the damage nodes. But if you aren't trying to get ALL of the Damage nodes just switch out Close Quarter Killzone for Grenadier.
