Every time I was in a fireteam the lag got worse. My shots weren't registering properly so I found myself having to shoot a few more bullets than I had to which would result in my death a lot. Couldn't even tell when someone got the spark. Took too long to come up on the screen. I went from about a 3.5kd average playing solo to a about a 0.5kd average in a fireteam. I am forced to fly solo because of lag.
