Well, as i see it a save command is absolutely needed, imagine having to log in and out every 10 mins just to get your char saved, wouldn\'t that cause more lag than the suggested save command?
Also I agree with you others that a timelimit would be necessary.
In the case of e perfectly stable server this wouldn\'t be needed, tho i have still to experience a mmorpg with one of those.
How does other mmorpg implement this?
