They should have the regular carbine from halo 3 instead of this crap. It is really rare for someone to get kills with it unless the opponent is oblivious to where you are at and that is pretty much it. You cannot go toe to toe with someone with it, if you do, you are dead, period. I tested this in training and went up against a bot that was using it and completely missed shot after shot. I shot bots with it when they are not looking and manage to get a kill.
The closes thing you can get with the thing is a shield down and that’s it. Like I said before, I rarely see people killing someone with it, hell not even using it. They should just either remove it completely, change it to a plasma rifle, or just buff it. Other then that, it’s pointless using it.
