Replace lazy ways to balance weapons with immersive ones. Delay on RPG and Javelin (why it even has it) can be replaced with more steps to load ammo. E.g. remove safety pin, and install missle slowed programmatically or with multiple interactions. Instead of lowering the rate of fire, it is better to increase the recoil, and possibly slow down the return to the starting position. This applies to the semi-automatic guns. These changes will improve immersion and reduce "arcade game" feeling
