One issue that I've seen brought up several times in the threads involved how the seige system of EU2 did not work late game. This true, but I think most people mistake the reasons for why. EU2 fortresses work by a system of gradual building up-meaning you must progress from the most basic forts up to the bigger ones. While this makes some sense, since you could build more on to a fort to make it better, it doesn't model how the changing nature of warfare in the period necessitated the construction of totally new types of strongholds which could not simply be built on top of the older ones. To that end, here is my suggestion: Make forts dynamic based upon the tech of the country it is a part of. For example, an eighteenth-century army would laugh off fortifications that hadn't been altered since the 1400s, so make it so that forts gradually lose their usefullness based upon the comparable tech levels of the countries involved.
This may seem like a very radical proposal, but it would do a lot to make later-game wars work historically, since later on in the game all of the older fortresses would stop being useful, making it much easier for the later forms of warfare to work properly. Also, it would make it necessary to actually pay attention to your country's defenses, because if they are too old they won't keep out even the neighbor's dog, much less their army.
Thoughts?
