In EU4, WC and conquest in general is a bit more complicated than in EU3 because the cost of not having cored a province is worse.
I think that the idea of spending power points to core is a good idea.
But I recall that in EU3 the core idea was the system that made you think 'this province has been mine so long that has become part of culture and heritage'. And that would happen passed 50 years.
I think that this coring at the moment thing has become more of a in-game gamey challenge and has lost its historical purpose a bit.
I like also that bigger provinces have a bigger coring cost.
If I were the devs I would combine the two systems. Coring after some decades should be automatically done, and the coring cost should be decreasing a bit year after year the simulate the passing of time. Also, small and unimportant provinces shouldn't require to wait until 50 years, it could be less. And coring mega provinces, such f.ex. Antwerpen or Venice, should be way more costly.
If you decide to wait you are to face many stability problems and so on, and you have the possibility to end the problem with a click.
Also, there could be various degrees of coring. For example, both Crete and Venice itself were cores at some point of the game, but Venice was for Venice extremely important, to the point that if the republic lost its capital city, it would disappear. The game for now isn't able to reflect this.
