Perhaps my favorite playstyle. Larping as Captain Price in the infamous Chernobyl mission fits so perfectly. Which is exactly why this issue is so close to me.
Firstly, focus hardly does anything. It was so easy to line up long distance shots in ItR1 because of how low the sensitivity made it. That low sensitivity saved my life at the end of the game on Ironman mode and it needs to come back.
Secondly, the large scope needs to be readjusted for conventional placement. When placed above the trigger, the picture is 144p and the scope shadow is insane.
Finally, remove the fog or at the very least let us see through it with the scope. I've had times where clear silhouettes in the fog can't be seen through the scope. But even with that, vision is still close enough that a high powered scope isn't needed most of the time.
