After the failure with explosive bullets for shotgun, due to imaginary FPS drops of wooden PC kids and overpower, I noticed the function allows players to use molotov explosion instead of normal ones that make your screen shake.
This kind of mod will make you unable to sprint when hit by an incendiary bullet. This will help every player fight those laggers and sprinters who manage to heal even when they sprint. We could also create a new craft item called "Incendiary Bullet" and make players able to use incendiary shots only when they have these bullets in their inventary.
This can possibly be extended to LS as well.
