2) The military system sucks. Vicky, which covers the period of mass, front-to-front warfare, should use the move=attack feature. This is quite simply a much better way of simulating combat, requiring less micromanagement, reducing whack-a-mole, and allowing grand battle plans and enciclement battles. Get rid of occupation time as well - it doesn't represent anything that really happened, historically armies took effective control of the territory into which they advanced almost on arrival.
The only point where that would make sense in Vicky is WWI, and only on the western front, which is a pretty small part of the game.
