Isn't this a bit too much? The defender has to wait 2 years before even starting to get WS from land control?
I don't think so, the Attacker needs a period to attack before the Defender starts racking up score from the Status Quo, and if they are doing well they can still gain WS in other ways. Still, it's a value in defines, so it's easy to edit if you want it to be less.
I read that as meaning that it would take 2 years for warscore to accumulate from simply not losing territory.
Exactly.
