Does anyone else feel that on winning a Crusade, you shouldnt keep both the Crusader Kingdom and your old duchy, stolen away from your former liege? Or for kings become king of two places?
Historically the Crusaders gave up their former lands, as is the only practical thing to do rather than rule on two ends of the continent and having to fight your former friend and liege at some point when you really need to focus on maintaining the holy land.
But in CK2.5c you suddenly and without warning become King of a vast kingdom, and king of a duchy or two in the middle of someone elses kingdom too.
What i reckon should happen is an on action event giving you the option of becoming King of the Crusade Kingdom at the cost of losing your old holdings to your former liege or if your a king then your old kingdom passes to the strongest de jure vassal or same dynasty vassal or something.
or keep your old lands and get a prestige and piety boost and have the next in line crusader get offered the same choice.
That way there would be choice and consequence.
As it is, it might be good for a player wanting to conquer the world, but it doesnt really make sense story-wise.
