Harder to use? It doesn't even agree to those terms. It's utter garbage, because It takes 7-9 headshots to kill someone with the carbine, and it's certainly a heavy disadvantage since the DMR and BR require half or less headshots for the kill. It's not easy to aim and fire headshots at a rapid succession to get a kill, much less 7 to 9 times. It needs a buff to be able to at least last against the two-most-used, and, of course, it's very doubtful that it will receive such a buff anytime soon.
