FFXIV: Stormblood Has to Logout All Players Once a Day Due to Congestion Issue
The launch of the new Stormblood expansion brought Final Fantasy XIV long queue and server congestion which were expected. To ease the congestion issue the game would automatically logout idle players who were away from keyboard for 30 minutes, and let those in the queue login. However a number of players used methods to circumvent the automatic logout and made heavy congestion.
To deal with that Square Enix announced to carry out a forced logout measure that will logout all players simultaneously across all servers once a day, and even you are in the middle of a boss battle or quest, you will be kicked out. An announcement for when this will take place will be made one hour prior via in-game system message. It sounded bad to me when I heard this but I thought otherwise after taking a second look. Previously many players intentionally stayed in the conversation with NPC to avoid being removed when they were afk. Others trie bypassing this auto-logout with different methods.
That said, I think this is Square Enix's issue and they should find a better way to reduce the congestion instead of kicking everyone offline. Afterall not every server has the queue issue and it does bring negative experience to players in a less congested server. What's more, there's no time frame when this will end.
