For me, I feel like range should basically be like this
Min Range: this is the distance the bullets will travel before fall off begins
Max Range: this is the max distance where falloff occurs, after this distance the damage stops reducing
Max Damage: the maximum damage your gun will do, call it close range.
Min Damage: the minimum damage your gun will do, call it long range, the distance between this and above is medium range.
So let’s say the M4 was like this
15 m, 30 m, 14 damage, 7 damage.
So up to 15 meters the gun deals 14 damage, then it begins to fall off till it hits 30 m, then it will do 7 damage and never do anything less.
If this is how it works already please enlighten me as to where the evidence is cause I can’t find it.
