Low end systems already had their Red Orchestra. Ostfront for example. Even in Ostfront faces didn't look as hewn from stone like the ones now. Surely in an action game you do not have time to look at faces and feel the lack of immersion. But RO2 is despite way more action like than its predecessors not an action game. I can recall countless times in which we were just sitting and waiting for the enemy. Then you have endless time to see how the eyes are not moving, without any expression, no fear, happiness or anger in anyone's faces.
Dying animations are there, you can see from time to time a dying soldier see spasm with his arms, trying to grab something. The whole idea goes bananas as the face expression actually makes you laugh, it's so hilarious.
Other blending animations such as throat shots in which cause you should grab your throat trying to keep the blood in would also require facial animation to be immersive and not ridiculous.
Personally, I do not need a new gun nor a new vehicle, I'd like to finally have something that creates immersion in moments we have at least 80% of the game. Infantry combat, killing enemies and waiting for them.
Same would go for the 1st person body awareness. Every time you look down to pick something up. Every time you mantle something you'd see your legs. Mantling happens very often.
