I was not suggesting that just being an hour in the queue would be the base for drop. If you were doing other stuff in the game, be it craft, beast dailies, market boarding.. whatever you could be in queue 24/7. My suggestion would just affect to those who have retained more than an hour of AFK status, thus most propably not being on their computer, even if the queue pops.
edit: My suggestion comes in same vein as those that suggest afk mentors should be kicked from the novice network after a while.
