most people that shoot more than 5 rifle bullets are spawncampers, people using rifle in close-combat, people stuck in wall duels, or people who don't reload often. Just reload when nobody's around.
Also the only times the RoF of the rifle is gonna bother you is when you are facing 5+ others heading your way. In 0.75 you could eradicate an entire squad with the RoF there, now you have to aim carefully for the head each shot, and take cover while being shot. I don't waste my entire clip on some guy who's close-mid range. With the new RoF you have to cool down and aim for the head once more, not use it like an SMG, turning the semi into a profs weapon.
Balance pls.
Damage falloff is unneccessary though.
