I can’t understand why gaijin make FCS disable everything about weapons for many vehicles ,i think that’s a silly ,boring and unrealistic idea.
First,tanks should be equipped with mechanical aiming and firing systems.
Second,for now if FCS was broken you can not launch any effective counterattack to protect yourself, which results in a poor interactive experience.
Third,FCS always positioned in front of the gunner, which makes it extremely vulnerable to damage，and that leads to my second opinion
So i think break FCS should not disable aiming drive and firing for most of the tanks,just keep it for tanks have unmanned turrets
