I think to make next strat better will be to make it closer to strat 4. Vote for fiefs, lower gear costs, speed up movement even more than it is now. When you quick march allow people to cool down sooner (like maybe 10 hours min, 15 hours max). Remove night time settings, and give the Chinamen their own strat map (make it small like NA if you need to).
I never understood why gold wasn't lootable on armies you defeat, it should be.
Also having some sort of end game rewards would be nice and encourage people to fight over fiefs (not everyone gets rewarded, only the top 1 or 2 factions, and it gets scaled down to how many people are in the faction).
