World scroll: one thing i remember from extebans server very well was a scroll that was housed by one of the three villages and when your village was in possession of it you would get event points, money, and xp on a set time interval (30 minutes to an hour i don't remember exactly) While you held the scroll while transporting it you would walk as if you had a flag like in capture the flag. This scroll gives reason for villages to compete other then just for the fun of it and I think its a relatively easy ad (said the guy with no experience in coding ever). Each village would have a pedestal and the scroll would sit on it. For missing ninja you could add a pedestal in cha for them to benefit from this as well.
