On the right side of your keyboard is a keypad. This is the VATs targeting system. Key 8 for head targeting. Key 5 for torso. 4 and 6 for arm targeting (disarm enemy if limb becomes crippled), 1 and 3 for legs (quit running away!), and lastly 7 and 9 for right-hand and left-hand held items respectively (pistols, hammers, grenades, et cetera). Targeting a specific body part or held item against a target in VATs will reduce firing speed by an acceptable percentage (20% maybe?). That way there's a tradeoff between straight DPS and disarming and crippling your enemy.
In this method we can avoid the FPS system (and dodge the aimbot problem altogether) while greatly boosting the tempo of combat within the game. With this method, a good player can choose a target, open fire, aim at a specific location on that target, and switch ammunition types as needed without having to spend an inordinate amount of time doing so.
