I cant hear the enemies footsteps!Also the Radar..

I cant hear enemies footsteps in this game…and because the radar is so useless you will often get surprised by players that comes out of nowhere,especially in BTB!Its so frustrating to be killed by an enemy squad shooting you from behind that you didnt even know they were there…Spartans are really bulky,there is no way that they make no sound while walking…Also the radar should get a buff in btb…And i think that enemie players should not get that red outlines marking them…
