It is just a formula. There is no set date.
To address the comment about about +100% cost -33% less effect... The double cost was 100% required because of it's effectiveness with armor. There is zero reason to spend it on infantry when the firepower you gain from armor is twice as much.
So I see it as armor was half the cost it should have been and now it is accurate.
It's like paying the same price for a cheap battery or an excellent battery. You will always pay the same price for the excellent battery.
But when there is a price differential then you have to choose based on need.
This beta will be for a while to make sure this mechanic is correct.
You are absolutely right Alvaro that Players used supply trucks primarily on Armour. But, of course, that was historically the units that received supply priority in the War itself for the very reasons you mentioned. Supply priority was always given to the mobile units.When supply was short in North Africa which units do you think received the bulk of supply (oil, ammunition, etc) that was available; the armour/mechanized units, of course. The same is true of Russia and Normandy. But even if you are correct that the cost for armour and air should be 2X that of infantry (and I can see where armour should cost more, just not sure about 2X), why double the cost for armour and air, why not halve it for infantry? And why the double whammy of also reducing its effectiveness by 50%. Personally I just think this was too drastic a measure (similar to the drastic cuts made to air units effectiveness), but we will have to wait and see.
