The economic advantage of one faction has no bearing over a fight between the two units when they are on the field, the OKW having less fuel income does not actually affect the Panther's ability to be a tank hunter.
It only effects the field presence/timing.
This is not to the guy I quoted but to EVERYONE
OKW FUEL ECONOMY is a factor..for TIME.
A non supercharged okw economy delays the timing of the unit compared to another factions economy. The reason why this whole cost more thing came up is due to the fact of by the time you have 175 fuel the other player would have 200 (random number example I know its not 133% of 175)
So no the tank doesn't cost 232, but the opponent fuel (unless economy supercharge or just outplayed) should have more fuel generated overall. Now next thing to consider is teching cost.
Just had to throw that out there I get a cringe every time the OKW fuel argument goes out there and its not done properly.
