So what if the are alternate variation of high tier weapons with practical difference ? Like in other games where there isn't just one "Assault Rifle" but there are variations ? Here's some examples to start it off:
Assault Rifle: Battle Rifle (Burst-Fire Rifle)
Shotgun: Double Barreled Shotgun (Higher firerate but only 2 shots)
Sniper Rifle: Anti Materiel Rifle (goes through armor)
Pistols technically already got their own high-tier variation
So it's just up to you if you have any suggestions for variation. I just thought of this because maybe the gameplay need some freshening up and variation, and also opening up more kinds of strategies and different playstyles
