I ran into this same exact thing tonight! I'm not über awesome at all. I go 1.5 to 2.0 in most games. Out of nowhere I get two tapped by a 103+ player with a blue non upgraded scout. It got really bad and I ended up carrying the team being on top with(18/7) or something like that. Granted Destiny is my first ever FPS doing PVP but in the last 3ish months the level of damage you take and level you output is VERY inconsistent.
