Hi, i've been playing halo 3 for quite a while now. I enjoy playing on live and i used to play and get a lot better. But recently I've noticed that playing has not been making me better. If anything i'm getting worse. I used to be amazing at sniping but now have trouble. I'm on a plateau and i can't fix it...what do i do to improve and move on. BTW this is important to me because i have a college wide tournament coming up!
