(Easy, Medium Importance) Allow a puppet to be released as soon as 2/3 of the victory points of the nation is controlled. For a nation without victory points, 2/3 of the territory. (This way, one won't be prevented from releasing a puppet because one or two provinces are not under control.)
(Medium, High Importance) Members of an alliance should not be able to be annexed while the alliance is still fighting. They should go into exile and if they are liberated, they shouldn't become owned by a liberating former alliance member.
(Medium, High Importance) Fleets which are losing a battle should only be able to retreat back the way they came. This would prevent weak forces from impossibly breaking a blockade. It would add a new strategic element in naval warfare, with the new and realistic possibility of being able to corner a fleet and destroy it. A historical example of this would be the blockading of the Spanish fleet in Santiago during the Spanish American war, where Americans first blockaded the port, then captured the town, forcing the fleet to try to break the blockade and subsequently be destroyed. This would allow a fleet to be completely destroyed if its port is blockaded and the province is captured.
(Hard, Medium Importance) The game developers completely laid an egg in designing the alliance diplomacy system. It is completely unrealistic to have an alliance fight to the last province instead of accepting a negotiated peace when the odds are stacked against them. Separate peaces should be accepted if there is 50% War Score extra, unused on the negotiating table.
(Hard, Medium Importance) The Sue for Peace negotiation feature should be available even in peacetime as "Send an ultimatum". This is when they should succeed: If Nation A is k times the strength of Nation B plus the strength of all of the nations guaranteeing Nation B, the enemies nation A is currently fighting, and allies of Nation B. K must be equal to 2(100%+War Score of demands). Thus, if I had 10% warscore demands, I have to be 220% stronger than the nation and all of its allies, guarantors, and my enemies combined. If the ultimatum is rejected, immediate war is declared by Nation A.
Some of these would be pretty revolutionary.
