Battle names, should be not provincial but place-desiged - i mean - it should be named by cites and villages (on the province of course) and it should be randomly taken... no more : BATTLE IN PROVINCE KRAKOW !!! (or even under the main city - maybe it would be, but normaly it is not, ussualy.)
It would be realy fine.
Also : Historical disaster events in provinces, and also : historical weather (it would be somehow defined but there should be decisions that would help to avoid some of them (like - flooding can be stoped if you have good system of canals - so it would be not a disaster, but a blessing

*)
*thats the reason i dont like PO party in poland - they could not let it become a real disaster if made in time - and would even become a blessing - because water would stop the draught that we have now... but - who cares...
PS: Maybe even i should made Komorowski 3 adm rather than 6 adm for that regard!!!
EDIT : He is such a ruler that you would want to send to war and pray that die!!! ;(
