Chepe said:Yes, but the priority button doesn't make this distinction. Hence, the problem remains.
Not really; to keep with your ETO/PTO example, prioritize all your ETO units and only pay only a % of your upgrade cost equal to the distribution of forces - for example, if 2/3rds of your troops are in Europe, only pay 67% of your upgrade budget after having prioritized your European units.
For reinforcements, pay the amount in full; they troops may go to Europe first based on priority, but they will get to the Pacific eventually.
After all, historically if a new unit was prioritized for equipment upgrades, they were similarly prioritized for being topped-off with fresh personnel, not to mention recieving training in the new equipment.
The system as it exists may paint in too-broad strokes for your liking, but it does work.
