Firing single shots from this gun gives you 70% of the performance of a battle rifle, and it's available by default. I'm not saying that it completely takes over the role of a BR, but the amount of performance and flexibility you lose for using one is too large when the SAW is available. Battle rifles feel mostly fine, but their bullet velocity is seriously lacking. The SAW without HVA has a velocity of 600m/s, while the battle rifles are at a carbine level 500m/s. Increasing velocity doesn't change much, but it makes prediction less necessary and the gun becomes easier to use. Obligatory NW5 ruins battle rifles statement goes here.
