so if okw had 5% of normal income and brits had 100 percent normal income, it would be still considered balanced? you'd still consider it cheaper even if OKW had 1 fuel/min and had to wait over 2 hours to build a panther? no? then where draw the line?
You're going way overboard with exaggeration and here is why:
Units are balanced around cost effectiveness performance in relation to other units and their intended roles.
If you have 2 exactly the same unit in 2 completely different armies with 2 completely different economies, then these two same units will still be balanced with the same cost effectiveness relation. 100 fuel unit will perform like 100 fuel unit, regardless if you get 100%, 2000% or 5% of fuel income.
If Ost panther and Ost Ostwind didn't existed, then MAYBE you'd have some leverage to argue their performance, but these units exist.
OKW fuel penalty exists to limit vehicle presence of OKW given same map control as opponent, it doesn't mean their units will suddenly perform 50% better because you go and try to slap invisible cost to cost effectiveness equation-it doesn't work that way.
100 fuel Ost Ostwind and 100 fuel OKW ostwind is still exactly the same Ostwind, OKW one won't be 50% more effective because of fuel penalty.
So yet again-OKW panther costs 175 fuel, its cheaper then comet, it have greater AT stats and protection.
What you aren't getting because of fuel penalty, you make up for with superior scaling, superior teching with free side bonuses all other armies have to pay for or pick a doctrine for and pay on top of it again and superior menpower based force(inb4 some mad man pops with volks again-they are NOT AI squads, you have multiple other AI squads for AI combat, USE THEM).
also, i'd like to state again, i'm in no way whining or thinking the match-up between these factions is broken or anything, i just dont agree with the panthers and comets respective stats considering their costs
I don't think you whine and I never said you do.
I simply believe you don't understand how cost effectiveness in relation to unit stats works and what its based on.
