Apart from that, I agree that NCTH makes auto-fire much more stronger compared to OCTH, but in the hands of a Merc with auto-weapons/machine gunner trait. Machine gunner Mercs using high caliber machine guns which can take x7 scopes such as FN MAG are generally more useful than snipers. Nevertheless, a sniper/marksman with 100 marksmanship with x9 sniper scope will always shoot more accurate.
