This is quite correct.
Experienced players argue about the minutia of the game, mainly because we just assume that you have the basics nailed down. What's the point in debating whether or not you need a division with 11 kph when you don't even have basic logistics sorted out?
That's actually where I'm coming from. "Basic logistics" seems to be getting the "basic treatment." It's abstracted, it's going to be Chinese divisions having equivalent capacities to American ones because... it's just basic logistics.
The supply system was opaque, but it was also serviceable. Say what you want about how mystifying the supply system of HOI3 could be, but it was the key to making or breaking key aspects of the war. Once you better understand the supply system in HOI3, you can do amazing things with it.
It should definitely be made more understandable, but don't confuse "The system is opaque" with "The supply system was not the backbone to the game" as you indicated in a previous post.
A supply system shouldn't require specialized learning. It should be manageable with a few heuristics that are native to strategy gamers. For example, "Supply travels on rails" is one of those things known to every strategy gamer since the days of cardboard hexagons. So why not use that?
Well, aside from the war goals problem, I'm not sure what you mean here. What is more fundamental to HOI3 than putting a good infantry division into action? Do I need to dig up countless threads where the utility of various foot infantry formations is debated? Hell, I even address it in the strategy guide as a fundamental part of winning the war.
Now I'm really confused. Ever since TFH came out, the range of possible division builds went up. The inclusion of penetration and the revamping of some brigades and terrain penalties makes choices interesting even at the infantry division level. I wouldn't even presume to lecture a player on the composition of an infantry division until I knew what country they were playing, who they were fighting, and where that division was being employed. French MTN divisions in the Alps have entirely different requirements from Chinese formations guarding ports from amphibious attacks. German infantry divisions with superior firepower unlocked are facing radically different choices than Soviet formations preparing to run August Storm. And this doesn't even begin to address the requirements of the Pacific.
I was reacting to higrosco saying that the composition of the logistical backbone of the division would have an easily optomizeable min/max number that every player would figure out super quickly. I was agreeing with the point you make here that there are so many different divisions from different countries in different roles that there wouldn't be an optimum number, just tradeoffs based on what the intended role of the division was.
