Q: Why do I need this mod?
A: By default, it's almost impossible to integrate a single title within one ruler's lifetime by using a chancellor. This makes the council task almost useless compared to other duties a chancellor can focus on. With my mod, a ruler, starting at young age, can integrate 2 or 3 titles.

Q: Is this mod balanced?
A: Yes and no. I have tried to make the integration time as reasonable as possible(it should still take about 25 years with a chancellor with a skill of 15). Some might find the values I used too high or too low.

Q: Why not give a boost to AI as well?
A: Border gore. I personally don't like AI changing the borders of de jure realms because it almost always ends up looking horrible. Including them would make AI realms more stable but at the cost of player enjoyment.

Q: Why don't you also change natural de jure drift?
A: Three reasons. Firstly, I would probably struggle to find the value that would feel right. Secondly, IMO, integration of a title should take active action of the ruler. Lastly, I personally don't like natural de jure drift, both for AI and the player. In fact, I don't like it so much that I have thought about modding it out of the game.
Edit: I have now changed it, increasing natural de jure drift time by 5x (100y > 500y).
