The time to kill seems to have changed since the alpha. It seems that it is taking longer to get a kill. I have had numerous occasions where it would take more than one shot with the m24 to kill someone or even take 4 shots with the MK14 ebr when it would normally take at most 2 in the alpha. I also had instances where i would shoot directly at someone and it either did nothing or the rounds were hitting completely off from where I aimed.
