Every MMO has done this in the past and then removed it because of the long term issues with other players. This Game had it at launch to deal with Login queue times and they have now disable since the game has leveled out for nearly all servers. Yes there are times when new patch drops and Queue times are hell. But AFK timer does more But Currently from what I'm seeing on Swagatanas the game server pop is low during the Pre 3.5 cause everyone is either playing FF15 or other games and waiting for 3.5 or 4.0 to be release.
I still get random kicks and D/Cs but I don't care relogin is not a big deal.
