I see no downside to a time limit either.. It wouldn't effect me, so im not overly concerned either way, that said if someone has sat inactive literally doing NOTHING for over an hour, I doubt they would care either, considering they probably forgot they were even logged in. I mean I leave the keyboard periodically, but usually im flying when I do so, (2 min to get a drink or something) I cant fathom staying logged in, minimizing the game, and not coming back to it for over an hour...
