In most of my servers, including my fort war, I have spent days trying to make it so that many rules did not have to be closely watched. For instance, instead of a "NO USING CHANGEDATABLOCK OR MINIGAME EVENTS" I simply use Script_DisableEvents to make it impossible to use said events. In the Fort War case, I even whipped up a little host only changedatablock event so that I could make a builder class. Unlike most builder classes, this one can't kill or be killed, and must change back to fighter in order to enter the fray. I figure, the whole "builder" idea is good in theory, but unless you can effectively enforce it, it's useless.
tl:dr Just wanted to show that if the host took some effort to properly control their server, many fort wars could be a lot better.
