You have no problem with what went on in that video? You have no problem with people completely missing you but getting hits and headshots? --- My sarcastic tone doesn't translate over the Internet, which makes me sound like an ass. Usually I mean no offense.
reticule red = shots register. what seems to be the problem? the hitboxes are huge.. but this has been a problem in every game after h:ce and its really not that bad in this game compared to previous installments (see: halo 2)
