What strat needs is a limit on max production points ever spent in a fief at one point (for example 1400 for towns, 1000 for castles, and 500 for villages), and then fiefs being respeced and losing 75% of production points instantly upon any capture. A food system to penalize endless troop stacking, allow for actual starvationbased sieges, and make villages matter (food should die out overtime so it is impossible to save it up for lengthy durations, possibly allow pp to be spent on increasing food output, villages should have way higher food outputs than castles and towns). Massive alterations in the economy (there are plenty of ways to go by this, the simplest being making everything more expensive) to make slightly lower than medium armor the standard, then have lower tier horses being made cheaper so cav still exist. Finally it desperately needs randomized fief distribution to make it less likely that every faction takes the exact land that they always take, and to hopefully cause enough tensions among players to make two megablocs EU style highly unlikely.
