Please, please, please....PLEASE sit and actually think about adding this into the game. Honestly, it's highly annoying there's no AFK system, but to be put into a 4 man after 45 minutes - 1 1/2 hours of sitting in queue for your tank to accept it, pull 3 mobs, then sit AFK is the most highly annoying thing ever possible. (Yes this happened to me. Our tank went AFK and came back 25 minutes later after I had to dragoon semi tank up to the first boss).

Can't leave the group or else you get a 15 minute debuff that refuses to let you queue. Why am I being punished because someone else decides to go AFK in a TIMED DUNGEON after I had to wait around nearly or over an hour?
