Only reason I could say it ok to avoid the afk time out if like if have to get eat dinner or something and the the queue to log back in would be longer then what you would be gone. So if you going to be gone for an hour and the login queue is 4 hours I could see that. But that ones I do find selfish are the one that leave their system on 24/7 while they sleeping or at work yea those guys are A##holes.
