More irredentist decisions with a proportional gain in infamy, such as a 54-40 or fight decision for USA or one that fires when Mexico is occupied to annex it for a large aggressive expansion/ relations penalty.
Also colonies should receive adjacent colonial provinces even if they aren't cored. I can't count how many times I've seen the British release Canada but keep Washington or Idaho.
Vickymod adds "54-40 or Fight". I chose "Fight" this game, and my troops fought 3 in the frigid plains of North Dakota and Columbia against the Redcoats and their Spanish cronies. It was fun.
It's not worth it to dramatically retard your development just for some snowy wasteland with nothing but wood in it (no offense to people in British Columbia), but it's more about sending a message to Europe, I think.
I too would like to see an annex Mexico event chain, IIRC some southern expansionists in OTL floated around the idea, hoping for an influx of slave states. If you were to annex Mexico, then you would get an alternative civil war where Northern abolitionists, tired of bleeding for the gain of Southern planters, declare their freedom.

Vis-a-vis the main point, this was reposted from my statement on Reddit:
Vic3 could be dramatically simplified and changed without sacrificing much depth. The problem right now is that there are a lot of cases where there's pretty much one correct way to go about things. And everything else is pretty much there to frustrate the player with needless complexity.
For example, National Foci: Bureaucrats --> Clergy --> Craftsmen, with Clerks and Capitalists as necessary, is the best way to go about it. The other Foci might as well not exist.
Another issue: State Capitalism is categorically the best way to start off the game. Laissez Faire is pointless and indeed deleterious at the start of the game, and pretty much exists to fuck over the player (though it can be useful lategame when you've built up factory infrastructure and a capitalist class). This is particularly bad for USA and CSA players, who can get stuck with the 100-year Conservative Democrat Junta (Whig for CSA) unless they use the rather gamey Election Spam (itself a problem).
Maybe the United States needs to have a difficult start to make up for its amazing lategame, but the CSA doesn't, and we can make the USA weaker without needlessly frustrating the player.
Another issue: conquering large Uncivs (Egypt, Abyssinia, Korea, China, Vietnam, etc) is categorically the best way to expand. Vickymod tries to fix this by adding some small states in West Africa, but it's still pretty bad. I groan when I see the British Empire taking both Egypt and Abyssinia, and France taking Vietnam, because then all that's left are table scraps. And it happens every game.
If I were Paradox, I would forbid all expansion into China beyond treaty ports. Regarding large Uncivs like Iran and Egypt, I would have players start with them as a satellite, and slowly extend their tendrils into the nation and turn them into a protectorate. To give other players counterplay against this, I would allow them to fund nationalist movements against the imperialists. This is [exactly what happened IRL](
http://en.wikipedia.org/wiki/History_of_Egypt_under_the_British) with Britain, Egypt, and Germany.
This way, the player has to choose between quickly grabbing the low-hanging fruit, or investing time and effort into large but profitable colonial endeavors. And this way, it's not gg for the German Empire once the British get Egypt/Abyssinia/Iran and start profiting ridiculously off the resources and millions of pops.
Another issue: Army composition: it's tedious as hell to always build and then assemble the correct amounts of Infantry/Artillery/Cavalry. There's pretty much one right way to build armies: fairly even amounts of Inf/Arty, with Cavalry on the flanks. So why not automate this, with an option for micromanagement-minded players to build their own armies? Or give the player the option to set the relative amounts of soldiers of each types in an army division?
TL;DR: Vicky2's problem is that in a lot of cases-national foci, economics, imperialism, military, etc there's frequently one correct option. In those cases, Paradox should either scrap it and focus their energy elsewhere, automate it, or add other viable options.
