All in all I like these changes, especially the revanchism thing, anything that inhibits blobbing is great. As for it being exploitable, they can either design the game to be fun when played as they intend or cater to rules lawyers, I prefer the former, if that means that the exploiters get away with it then so be it. People who uses the console also gets away with it, and quite frankly I don't care.



As for the development change it's nice but considering military expansion and coring is already a better use of monarch points this may be adding to that problem. Playing tall seems less feasible. My solution is this, decrease the overall costs of development so that developing aprovince to a development level (from suposed scratch) costs about 10% less than coring a province of the same value. And then add a modifier where either war exaustion or being at war or having a peace treaty increases development costs up to those 10%. That way the nations who expand by development and colonisation has an advantage when it comes to developing compared to those who conquer.

That and make more ways to turn gold into monarch points.



As for capital movement, there has been some nice suggestions here like having the decreased development cost tick up over time, and having it be cheaper to move to a more developed province.

I say do it all, tone your version down a bit AND have it tick up. Plus it being somewhat cheaper if you're moving from a less developed province to a more developed one.
