Being shot at the back needs to be a little more obvious

Multiple times when I’m being shot at the back its not immediately obvious to me.

There;s no sounds when I’m being shot at the back vs at the front and the sides and when I realized this its too late.

Is this a bug? I can’t even hear other players behind me, and now that I mention it I don’t actually hear a whole lot of foot steps at all.

Maybe some more ambient sounds or tweaking to volume when getting shot to remedy this?
