The supply system in HoI4 is basically nonexistent. It is either "you have enough infra and provinces" or "you don't have enough", and as in HoI3 the AI is not able to recognise if it's placing to many troops in an area.
While I like quite some aspects of HoI4, especially production and division templates, it is not nearly as interesting on the Wargame aspect. Either you put up a plan and an army to execute it (with a horrible interface, sorry to say that but the planning interface is a mess, at least for newbies) or you try to command your armies manually, which results in a clickfest far worse then HoI3. In HoI3 you had to click a lot...at the beginning. The rest was done with a good organised OOB.
I for my part loved to command my armies in detail and historically correct, at least until Barbarossa. In HoI4 I do not get enough info and OOB structures to do so efficiently, and I am happy if the Soviets don't declare war on me in 1940, with historical mode activated. So, compared to HoI3, HoI4 is en par. Not better, not worse. It is what it is...but it is no HoI for me. It is an WW2 Sandbox.
