The DMR is SLIGHTLY overpowered(needs to be SLIGHTLY less effective at close range, ie lower ROF). The Carbine is underpowered, while it has the highest ROF and no bloom, it has lower accuracy(and damage, but the accuracy is the issue here) than ALL the other precision rifles, so much so, that it only beats any of them out at close range and maybe close-med range. Other than that, the rifles are pretty well balanced, now if only we had more maps.
