Regardless of class, stickies are the way to go here. Flux grenades for Hunters, Fusions for Titans and Warlocks. Titans want Armamentarium, Warlocks want Starfire Protocol, And Hunters want Frosteez. Four grenade cooldown mods. And the cherry on top is the Chaperone. Body shot an enemy with the Chaperone, lob a sticky at them and be on your way. Chaperone body shot gets them primed for the sticky to kill them, and Chaperone Range is the perfect range for sticking grenades, not too close, not too far. Getting grenade kills at the same pace as my Super kills.
