I detected massive changes in my games when my batteries in my controllers where dying. When you start running out of electricity from your batteries the vibration setting is disabled. I played two games of big team battle, and i got 17+ kills on both of them. Before, the vibration kept on moving my hand, which then I couldn't focus my shots correctly, getting less kills, now on each game with the vibration off, I get a minimum of at least 10 kills. What settings do you use? On, or off?
