We've all seen it, a "Away from keyboard" teammate, and one very lucky sniper comes into your base, and keeps killing him over and over, giving that certain team more points, and possibly an air strike. I believe that the increasing re-spawn does help to an extent but not very long.
Now my idea to improve this, or prevent it entirely from happening is a simple click system, when its time for you to re-spawn you must click for you to do it, instead of just re-spawning automatically.
But! To prevent people from joining the other team, and not click, to help the former team win, there could be a auto-kick system in place for a various amount of time.
