Instead of fooling around with the qualifications of a tribe required to achieve the requisite 80%, how about just fix the endgame scenario to run as advertised? The Kingdom idea as presented on the Wiki is what drew me to this game as far as staying in it for the long haul. It would add flavor to it that is missing now. At some point, everyone will start to eat every village they can, just as with the other servers. The capture-the-flag idea of the Kingdom and Fortress options adds much more to gameplay dynamically.
