I play on a RP server. Part of the fun are the conversations that take place. It is nice to stay logged in and pick right up in a role after reading what has been going on. So being AFK for a few hours makes sense from that standpoint. The AFK issue arose because of SE not having enough capacity due to player demand. If people had been able to login and and not get 1017 errors this would be a non-issue. As it is, I personally feel 30 min is too short.
