Dont have the beta but have been avidly watching on youtube. One thing that I hadn't picked up on before was the metallic feedback sound when you score a headshot. Seriously? You can headshot someone at 200 yards and you get some daft, cartoon ping sound simulating you hearing the bullet as it strikes the targets helmet? I hope this is a bug (at least the current super-loud noise when you get hit makes sense even if it is a sound bug).
