We used to have an f top, but it broke and they don't want to add it back because the plug-in doesn't support it. I'm pretty sure the entire player base would agree with this suggestion though.
While I'd like to have a way to track which factions are on top, there are just no decent plugins for it at the moment that support our version of Factions. If a suitable plugin were to be released, or the current ones updated to work better, I will definitely add it to the server.
