Well since I think Dupers would backup their guys like every five minutes anyways I don't see how this would really affect them. I was a old school diablo player which had more duping than pso ( mainly cause it was a lot easier to do) but you will survive. It does suck for all those who liked to trade. Maybe the servers can find a way to scan players for duplicated items like a twin brand with certain percents and match them maybe even with the item code like diablo did. I have no idea how the game is run all I know is its fun to play. If some of you are sick of Dupers and traders make guilds where it isn't allowed that might help. then again I dunno it just sounds to me like the new server settings are mainly going to hurt the back-up's.
