There are (were) over 5000 weapon variations. I don\'t think simply changing the slash is an effective method to use.
Players have been given warnings - there are sticky threads, there was a server MOTD, there were news that a wipe will happen on the news page, though granted it wasn\'t posted recently.
The point is that you are playing a game in very early development, when things are the least stable. Should the devs inform you of everything that\'s going to happen, ever, and wait until you\'re all comfortable with it before proceeding with further developments? That\'s slowing things down quite a bit. Perhaps when we\'re closer to Beta stage, the developers will take more time to announce great changes before they happen, but this particular weapon wipe has been discussed to the death.
Please try to deal with it as best as you can, and remember - you\'re only paying with your time.
