Dude you fired 4 bursts. From the hip. You really think you did that much damage? I dunno what hit him but something did. Not you. You can even see how little damage you'd done when all of a sudden his shields are gone and he's at like 3/4 health. He probably got sniped. No offense, good kill but you're delusional if you think it was all you. And if you think it was, do it again. In fact, I'll go in Rumble with you, charge my super, and let you 4 burst my ADS to the head, and melee me. 4 bursts and one melee. Sorry bud but it's not happening.
