some thoughts on the weapons:
DMR- most useful gun, most powerful, most reliable
BR- pretty good, not useful enough. the recoil makes it less reliable at medium range, can only really compete with the DMR at close range
Carbine- straight up needs a buff. I can count the times I've used it and the times it's been used against me on one hand
Light Rifle- I don't really know what's up with this gun. I don't know if it's the reticule, the amount of feedback, the recoil, or whatever but this gun just seems inconsistent
