I think you don’t understand what AFK means.
If I am sitting sleeping at hive, I am doing other things. Reading this forum. Talking with a friend, watching a movie. Perhaps even doing something IRL and perhaps truly being ten meters away from the keyboard. If I heard a weird sound, I return to the PC. I have been playing this game so long that I have an internal clock that tells me when the evo timer is coming close. So I return to evo T2 and then do something else for 5 minutes to get T3.
If I wanted to play, I would be doing whatever you are saying. The thing is, I dont want to.
