Agree with you. Sometimes the AFK is a program. I have seen a player, jumping occasionally and shooting occasionally but not playing. These need to be reported to Origin EA so they can be stopped.
People leave for all kinds of reasons, including dinner calls or even disconnects when the phone rings. That would be impossible to fix, but there is a timer ruining for activity.
One way to fix your people leaving is to make friends and them enter the game by joining them, or invite them and go in together. You will at least know who you are playing with and they will likely help you!.
Hope this helps.
