its more fun to scam the really rich people, 1 get better stuff, 2 totally disgrace them, cause if they are that rich they should know the tricks of the trade by now
One final point I'd like to make. Only assholes who don't know how to play and are to stupid to be able to get their own items scam. Scamming is for retards who don't know how to play the game, simple as that.
ANyway, the second rollback method takes a long time, and if your rolling certain runewords, you better clear up at least 5 hours. Each roll takes 5 mins.
