ZM3 Points issue

There is an issue regarding ZM3 points.
Only the damage output from your gun will be counted toward your end of the round grade, and for some reason it does not include your special weapon's damage (turret, attack drone, claymore..)
So it results in special weapons taking away from points for your crate rewards.
Its just a bit annoying that if you use a stronger special weapon like attack or gold drone you will have a harder time getting a better crate.
