– Mending the Schism by getting back in union with the Pope. I know some folks will dislike this but, after all, it wouldn't be obligatory for players to follow this way but an alternative to the restoration of the Byzantine version of Pentarchy. The theology here was much more complicated than it seems, as the initial Popes of Rome were Greek for a very long time and even Pope Zacharias who crowned Charlemagne was Greek. Filioque came from the East, too, it was not invented in Rome. Many emperors tried to restore the union and, in fact, even Michael VIII, the former Nikaian emperor who took back the City in 1261, was, at least at some point, in union with the Pope. Constantine XI died Catholic. Marriages and potential successions were another issue. For example, a king of Hungary could perhaps somehow have displaced other contenders in a more convenient situation.
– As always, marriage AI. By this I absolutely don't mean there should be no inexpedient or downright bad decisions but if they are WAD, then they could, for example, trigger a notification or event to make sure the player understands this is part of the game flavour and not poor AI (e.g. the heir of a multiking acting like he's a normal duke).
– Attrition/army sizes etc.
– Army movement AI to avoid walking into other armies and dying to attrition where a circular path can be taken or ships waited for (notification?). Especially allies can be a pain but also neutrals when you need to wind up sieges (good if it's at the coast and you have ships at the ready) because a big stack is rolling overland using the most direct path.
– When you have a matrilineal bethrothal and AI won't accept a matrilineal marriage (any more), perhaps AI could/should make an offer to change to regular instead of either 1. leading you on, 2. breaking off and instantly getting betrothed to some other character?
– I'd like to see the mother's culture and lineage reflected in child naming proposals, especially for children other than the first son and especially when the mother's dynastic prestige is much higher and/or she has some really spectacular male ancestors.
– Perhaps some AI tweaks for people with the largest surnames. For example, historically, you wouldn't see a Rurikovich that wasn't a prince. There would've been no "Ritter von Salian" working as a bishop's steward or baron's marshal. Accepting a patch of land and technically being a vassal is something I could see but in most cases I'm inclined to think a Capet would not be kneeling to a Dampierre or a Plantagenet to a de Vere, even in the presence of, say, an obligation to provide levies or some such.
– I'm kinda missing two things: 1. abbots and abbesses (way for female ecclesiastic vassals), 2. lawsuits for claims before the liege or king or Pope or Emperor, where the moral authority of an emperor not being your liege but still being a higher tier ruler could show (as well as that of a 5K prestige or 3K piety equal or even inferior, esp. with the Just trait). These are probably more DLC matters, though.
option to create titular titles
Might be a good thing when a son's rank would drop too low in gavelkind.
Also would be nice to fix that attritionless doomstack army trouble. 200k men walking in the desert without any trouble seems awfully unfair and broken.
Definitely, unless they have good provisions.
Probably been said already, but death in childbirth.
+1
Do Want: Anglo-Saxon England as an elective monarchy, Eadgar 14 years old in 1066.
Don't Want: 19-year-olds dying of unspecified "natural causes."
+1 on both
BUT, a "mysterious" or "inexplicable" cause is still okay. Just not natural, I think.
Fix the fatimids. I have now stopped playing, because of the ridiculousness of having a fatimid greece every other game.
Remove Invasion cb. Holy war is good enough...
Remove Shia jihad. Shiites did not jihad, and since orthodox dont get crusades either, I dont see the necessity of shiite jihads.
Give Fatimids higher decadence. Their empire was on the brink of collapse.
They were sort of defensive allies with nubia. I know paradox has no intention of fixing this, but I just wanted to bring it up.
Jihad (also sunni) should not be able to target non-bordering lands. Jihads were about reconquering islamic lands, not about conquering places half way across europe.
+1 on there being too many CB's for Muslims. Invasion, jihad, holy war, even the semantics here are problematic because of how far those terms overlap. It does produce a certain sense of redundance.
And bring back the Defence of Faith CB, please! Just make it conditional upon character traits or something else in AI scripts to prevent abuse if you think it's too powerful. I often want to help out other Christians but I don't necessarily want to go through the technical requirement of declaring a holy war on some of the Muslim's territory. Besides, I neither want to capitulate after achieving my goal (i.e. the Muslim power drops out of the war on the Christian target) or actually need to defend the new conquest and deal with rebellions. CB would be fine. You'd be gaining piety and prestige, and opinion boost from certain characters, and maybe a character trait (such as the Crusader trait as being an exceptional circumstance where you'd get it without participating in an official papal crusade) and nothing really more. Which is fine by me.
Also:
CBs for helping out relatives, especially closer ones.
