May I suggest that how often you duel the same person be changed from 1 hour to 3 hours. This would make it possible for the weak to do a 2 hour job without getting knocked out by one guy on a vendetta against them, while still allowing the strong to attack those they consider to be deserving 5 or 6 times a day without losing sleep. Even the most aggressive of us can agree that is more than enough times in one day. I am making this suggesting after being chased around all day every day by someone who isn't even mad at me, who dosn't even want money or experience from me, but rather wants to lash out at one of my town members who he can't beat, through me. I feel I am a third party facing the consequences of other peoples actions, and while it wouldn't be fair to say stop them altogether, it is not outrageious to ask that there be a long enough break inbetween to do a 2 hour job. In general, most people are incapable of limiting themselves, so I suggest that a rule be implemented into the game limiting the frequency in which we can attack the same person to once every 3 hours. This of course does not apply if you are attacking different people each time. This rule also would not prevent multiple friends from getting together and all attacking the same person at the same time.
Please do not interpret my commments as a personal attack against anyone here, it is only a suggestion and not meant to hurt anyones feelings.
