30 Minutes is hardly short, your essentially saying, the AFK Kicker is too good at identifying I am AFK fix it so I can remain AFK.

The AFK Timer functions for a lot of reasons. 1 to keep the population of the server on controllable levels. 2 to handle any type of state n the future where servers may fill, Expansion, Update, Etc. and Lastly it helps the servers only apply resources where they are needed, 100 people AFK in a city stealing resources from a zone that has a huge FATE, or a large population clearing is poor resource utilization.

They have incorporated a feature to improve the general wellness of the player base and the reliability of the servers. and your raging because you cant watch a show while Q'd for a dungeon. if you dont want to have to worry about the AFK timer, check in, people miss the accept button all the time for Q's and its due to AFKers. this will just improve the dungeon finder reliability too.
