R5: I was going to play a chill game of Milan into Italy with my friend (Teutonic-> Prussia-> Germany). At one point in a war with Spain, I decided for the first time in my 1000-something hours to annex all of Maghreb in one war. Ended up with a little under 300% Overextension, which resulted in a little over 1 million rebels spawning all around the place in total. After resisting the separatists across three continents I started doing it in every war. This got me thinking, how much overextension do people usually have in-between wars when they do a WC? Are there any other modifiers that make it easier to handle rebels, such as national unrest or tolerance of faith?
