I thought about doing that and I've heard other people talk about it aswell. I didnt end up doing it, when I'm afk for that long I dont have time to play/dont want to play anyway. Queue time ease up a bit when that would become relevant for me anyway. I understand however not wanting to get logged out if you need to take care of something irl and then dont want to be subjected to a 5 hour queue again. If SE cant/wont provide enough room for everyone, people are going to set out to do something about it.
