Algiers was my protectorate (very very annoying that they all the time cancel the protectorate-status without you getting notification).
So, they were my protectorate on and off. Now they embraced Renaissance and I allied them. I want to offer vasallization now.
But economic base bullshit is a problem.
I have this formula from the wiki, hope it will show, when I post it, But its too complicated. I have no idea how much more base tax or production I would need so that my target accepts.
REALLY a good suggestion for paradox: Show the player how much more tax and/or production is needed so that the target accepts!
So, Algiers has 4 provinces with 40 development. And they tell me Economic base compared -71. How much have I to develop or annex, so that they will agree?
