I would play a different game if one dictated how long, and or often I played. If it was free to play I could see, but as long as customers are paying for game time I do agree that it would cause a lot of havoc (even more so now.)

That being said, I'm not against kicking folks that have been away for excess of an hour or two- but I really don't see it fixing anything to be honest. There are just that many people wanting to play right now, and even if you kicked afkers here and there, those spots would fill very fast.
