Stategus needs work, rework the castles and all that. Battle is fine how it is, Stategus needs a lot of love.
The 3rd vote option you would see a lot less of compared to the 1st vote option, so 1st.
Not to mention there still a lot of castles and fiefs with broken shit in them. An example would be one of the sieges on a fief that TKoV had recently where Hospitallers attacked them and one of the flags were unreachable and couldn't down it since it was 1 way wall.
Another would be the steepness of certain castles and how it breaks siege towers. Fix wooden walls while you're at it but I doubt that's a map thing.
