Three things I wish for that are to complex for any expansions:
- No provinces
Who wants to keep tabs on 15k+ of them anyways? Well I guess a few can be kept for administrative purposes, but HoI4 would be truly unique as the only realtime wargame of this scale if they allowed division movements to anywhere on an open map.
- Separation of strength into men & materials AT guns or Stukas won't kill large amounts of soldiers just like machine-guns won't kill many tanks. A tank division or airwing can be all out of working vehicles even if most men are still alive. Land divisions dependent on vehicles for say movements would perform like normal infantry without enough available.
- Tank/Plane count By producing individual tanks/planes instead there is no distinctions between reinforcements and new units. You suddenly can't go from no production to hundreds per day/week for reinforcements becoming ready instantly. If your tank/airplane reserves are out and you didn't keep assembly lines running, bad luck for you since a these things can take months to build.
I'm not asking for hundreds of different units and micromanagement to be added, but some basic abstractions like tanks/trucks/guns/fighters/light bombers/heavy bombers unit counts might be enough for example.
I agree. The 1st panzer div has 120 Pzkw I in 1936, then changes to 90 Pzkw I and 30 Pzkw II in 1937... as they are built. Send the 30 Pzkw I to reserve.
Same with planes, and improve the reinforcement system. Is not the same reinforce a Panzer div than a Infantry division. Assembly lines is a great idea. Also you would need a time to refit the assembly line when a new unit is available to build (change from Spitfire I to Spitfire II, or IX... whatever).
So factories to build tank /planes should be created (and can be targeted by strategic bombing). They should use IC and resources to work.
Change division build table. Most important units of the division are brigades/regiments, but add some specialiced batallions (AT is a batallion, not brigade really, like TD, ENG). A division should have 2-4 brigades and up to 5 support batallions (including transport, or medical support, communications...)
Generals should have a chance to die when the division is in combat, depending on combat situation (more likely to happen when encircled, less likely when attacking...)
More options for naval battles: give order to dissengage or pursue a retreating fleet, close or mantain distance with the enemy depending on speed of the ships. CV should be surprised sometimes by surface ships, can´t be sunk now by BBs.
Improve supply system. You must have supply production centers (like factories), and then you decide where to transport those supplies (train, road). Build railroads (now there is only infrastruture).
