Erton, I just wanted to say my roommate and I have followed a few of your suggestions and I've definitely noticed a sizeable improvement. Thanks for all your advice. Still a looong way to go to get elite but the game has become more fun now.
Looking to boost in: Mortal Kombat, Assassin's Creed Brotherhood, Black Ops. Send me a message over Xbox Live if you'd be interested. I'm online intermittently but can try to adjust my schedule for you if needed.
Please send me a message before you send me a friend request online, thanks.
