Based on what the suggestion is, this wont be helping much. People who stay at the back just wait for cops to push, they minigun, and when the robbery ends, they flee away like a mosquito. Thats just how the system is. Yes I get it that its frustrating to see them chilling and while you are struggling to not let cops invade, but you simply cant change their will. 1 min afk wont do much because you can simply move around a bit, and I dont think people ACTUALLY go afk in ARs. Probably stay like sitting ducks watching two sides fighting each other.
Anyways my vote will be negative as this doesnt help much
