Understood. Will wait for the final shape before concrete suggestions on military fiddliness.
Another suggestion on 1545, though, is that Princess Mary has self-loading baggage on two of the coalition axes, which should be represented if she’s your opponent.
Under the Foreign Enemies, “if (heir2 = “Princess Mary”) and hapsburg <70”, then the Hapsburgs should be your foreign threat. Mary has baked-in support from the Hapsburgs, and detaching them from her should require very strong ties.
Also, under religion. If you’re opposing Mary, then a moderate player should become an enemy to the Catholics (because Mary is absolutely going to make a point of her religion to draw in Catholic support, and a moderate player will get the “hell no” vote from Protestants), and a Catholic player should face a non-religious war (because both are ultra-Catholic and there’s no Protestant candidate). It particularly makes no sense for Mary to lead a Protestant opposition.
On that note, instead of “extremists” as an enemy, I suggest simply removing the religious axis from a war where the player has managed a moderate position. A coalition of ultra-Catholics and Puritans doesn’t make any sense, but a war that isn’t about religion, where people pick their sides based on other issues, does.
Another: Don’t use fairmath with victory and adversity, because bringing the stats in question back to normal after the event will leave them changed towards 50%, which is really damaging if you’re on a roll.
Bug: Allying with the Dutch and Protestants involves a Celts check, - I assume that was supposed to mean (dutch > 67).
