At the moment, when I use freelook and try and look over my shoulder behind me, instead all I get to see is my shoulder. It's as if I'm a hunchback or have got my head tucked into my chest, so that when rotating my head my shoulders are at eye level.
I also notice that my shoulders/upper body doesn't attempt to rotate at all, when looking over my shoulder/behind me.
In real life, when I rotate my head to look over my shoulder behind me, my shoulders are at my chin level, way below my eye level and so I can see quite clearly over my shoulder, even keeping my upper body/shoulders facing front, to at least 135 and 225 degrees.
If I want to look more directly behind me, I can do so just by allowing my shoulders/upper body to rotate a bit.
I find the current method not only unrealistic but it hampers gameplay as it means I can't quickly and easily check over my shoulder to check where my squadmates are but have to actually turn my whole body to face behind me, leaving me exposed to hostile fire from the direction we're moving in and making me have to turn back if we come under attack, increasing the time it takes me before I'm able to return fire.
