I'm 100% convinced bungie alters it intentionally. They'll give less skilled players "look ahead" advantages.. Basically puts them a little ahead of your game.. that's why you'll die in what seems like 1 or 2 shots.. Ever get into a gun fight with someone and land nothing but headshots.. but you die and they walk away with some shields left? That's bungie nerfing you to keep you at a 1:1 KD and 1:1 win loss.
