there's so much cool stuff in this game, but when you play online and shoot someone 5 times only to have them turn around and kill you with what on your screen looks like a single shot is incredibly frustrating. it'd be tolerable if it happened only once or twice a game, but it happens almost every single encounter i have with an opponent
i want to keep playing and hoping that it'll get better but it hasn't so far. it's kinda depressing.
it's also pretty frustrating to be getting shot, get around a corner and then about a full second later dying to the person even though on your screen you were out of his line of sight, and then on the killcam you watch him shoot you and when you die you're maybe a foot away from getting around the corner
i know the killcams aren't accurate but the difference between what happens on your screen and what the game actually thinks happens are significantly different and it ruins the game.
