Eazy-mode weapons. Mobility while firing means they are hit less, accuracy means they hit more. The small reduction in damage doesn't offset how often they hit. The weapons are effective at all ranges, so they are able to strike targets more often. The heat mechanic is amplified by their ability to take effective ranged pot-shots which aren't just a waste of ammo. They imagine themselves to be better players and more organized because everyone needs self respect, and admitting their advantage would be a blow to their self worth. Anyone who plays all three factions knows that VS isn't any more organized that the other factions. That head shot advantage for the NC makes sense: the high vertical recoil means shots that are aimed at the chest, (or even the feet with the gauss saw) end up at the head.
