I can't agree at all with any of this. Like, you start out essentially describing how much you enjoyed that there was next to no creativity in battle (everyone using EXACTLY THE SAME 20w or 40w divisions, and therefore probably exactly the same doctrine, superior firepower...) Then you go on to complain that "micromanagement not tactics in the actual ware determines the outcome." Well you essentially said that already! If everyone is fighting each other with mirror armies, with mirror doctrines the edge goes down to micromanaging now doesn't it?
We live in a world of games getting slowly dumber and dumber and your complaint that this game is bucking the trend?! Why? Why do you want a game that is dumber? What possible reason could you want FEWEER OPTIONS for!? If that's the way you like it, just turn off the game and play age of empires! Oh wait, there are multiple strategy options available in that game too! Oh no!
I have played every single HOI game since the original, I remember the original with joy in fact. What was so refreshing about HOI4 was that they didn't decide to dumb things down for once, they added a HUGE volume of complexity. In past games the game would tell you that "a division of this type costs 4 IC, would you like a brigade with that? " Then you dedicated some IC to generate "military supplies" that served to both support and replenish the losses of every division type, even tanks!
When I got HOI4 I discovered a much more in depth world where you had to scrounge and find the gear your armies would use. If you didn't plan appropriately you easily could run out of tanks, and some equipment just wasn't in the cards due to resource limitations (a real factor in the war.) This even opens up new tactics. You focus on expensive heavy tanks, I make motorized anti tank and cause so many heavy armor casualties that you can't keep it up anymore! It's amazing having OPTIONS because in past HOI titles I could never dream of removing all your tanks from the field!
Each DLC has added more layers to what was already a delight. Puppeting became honestly one of the ideal methods of power as it was historically. Focus trees were added making even backwaters like Manchukuo interesting to play. The naval expansion is like a whole new game in itself because of the sheer number of options it brings to the table. Navies now can be custom tailored to the country's mission. That's a good thing.
Your complaint about not having a money stat is another contradictions. Do you want complexity or don't you? Of course the money stat ultimately is meaningless. In HOI 3 you'd assign factories to consumer goods, generate money and use that money to buy off the international market. Now you use factories to produce consumer goods for export to buy off the international market, it's the same thing! Realistically your money is only worth a damn if your making something in your country that other people want and can get with said currency. So this is the most honest and straightforward implimentation. Because HOI4 eliminated resource stockpiles outside of fuel they removed the stockpile of currency to prevent a sophist's workaround of a lack of stockpiles. The lack of stockpiles is supposed to mean you stop getting the resources you want as soon as you stop shipping something out in return, but having money to stockpile means you could continue to import even after stopping exports. So money had to go.
Why were resource stockpiles removed? I'm not sure, maybe they really aren't all that realistic. It's hard to believe one could stockpile enough steel and coal to make a years worth of American tanks and have this big pile of material in kansas or something ready to use.But I may be wrong on that one.
Anyway, I digress there. It seems to me that this is just you hating that things have changed. The complaining that more options are being added to a game about having options is so freaking irrational that I cannot believe that is the root of your complaint.
added: I did realize a reason for them to eliminate stockpiles and consequently remove currency. In the current game system you can trade your natural resources on the global market for IC, something that is actually useful. In the past all you could get was money, which basically was only good for buying resources not IC which is often what you really needed.
