I gave up on Halo 4 a while back for this very reason. The lag just make this game unplayable. But today I decided I would try again. This time it would be different. I would not lag; I would play a decent game and, win or lose, I would have fun. After six games of lag, I slammed my desk with my fist and vowed that unless someone fixes this bullshit by the time Halo 5 is announced I won't bother buying it. Simple as that.
