Just a heads up. If you're shooting at a guy, and another enemy walks out from behind the guy you are aiming at, your crosshair shouldn't begin following the new guy for no goddamn reason, that only serves to throw off your aim and hinder your performance. Once aim assist has locked onto an enemy for you, it shouldn't "switch" what enemy it's locked on to unless the first enemy dies or the player intentionally moves the crosshair in the direction of the new enemy. If anybody disagrees with these words, then please leave comment saying why rather than just downvoting and leaving like a jackass.
