Ideas
I was standing against a wall the other night at the edge of the Empire map and all I could hear was footsteps behind me. It's impossible for anyone to be there, it's not accessible, it's literally the edge of the map. Finally I see someone 50 yards in front of me. I shoot them and the footsteps stop.
I also heard the roaring sound of a tank practically on top of me when I was in the second floor of a building in Cairo, the tank was on the map over 100 yards away.
Sure the footsteps and vehicle noises are louder, but it seems the positional audio is far worse than before the update. It confuses me so much I have to turn it way down or I won't pay attention to where players are on the map. All that seemed to be done was cranking up the already confusing volume.
