Hey there JackLine
The AR-57 changes were applied on last week's content update patch as the AR-57 Headshot Damage multiplier was reduced.
Not sure if that's what you meant or nerf the weapon a bit more.
"nerf the weapon a bit more." 100000000000000000% pls cause its the same on the sniper rifels some ppl just always can do 1hit kill (even if you take the armor skill and faster heal or so .. uncool )
