Smoke Grenades for "Stunning" enemies and blocking LOS (Reduced sight range of enemies in the cloud means they often stand around doing nothing for the duration). Executioner's stance + Deadshot ADS helps with hard targets, but you can three-shot most human-sized enemies even when hipfiring. Bodyshot maulers to take advantage of weaker armour on the chest. Crits not consuming ammo gives decent ammo efficency even when hipfiring, so you can spamfire into hordes at head height to regain a bit of toughness in a pinch - tagged elites give pretty much all your toughness back on death.
