Warfronts should have the same AFK detection as Battlegrounds

People are able to afk the entire game and don't even have to return to their keyboard to move the mouse, as the away tag does not kick them. This leads to people being able to queue up, accept it, go somewhere like the mines, and leave their computer to go about something else.There is no punishment, and since they wouldn't have gotten a reward anyway, there is only a benefit. The chance of getting caught exists, but it's the same result as not queuing up in the first place: no loot. The only thing stopping someone from doing this is morality, and I keep seeing it.
