Reducing their fuel to 0 is probably too far in the other direction. Every other faction can make some sort of teching decision within the first minute or two of the game: Brits can get t2 or upgraded squad sizes, Americans get grenades, weapon racks or an ambulance, Soviets can get t1/t2 or molotovs/AT grenades, Ostheer can choose to either get t1 or save up for a quicker battlephase 1. There's currently strategies that incorporate such decisions: brits often get early squad sizes vs ostruppen builds, americans can get early grenades sometimes, soviets can stay T0 for a bit with molotovs or tech up early for other stuff and t2 rushes with ostheer are pretty popular now that MG's are t0.
OKW can now do fuck all. They need to gather 45 fuel to make their first possible tech choice. This means that the only build order diversity you have is going to be manpower based. They don't even have anything to spend munitions on other than mines and sweepers (outside doctrinal stuff like flamers) until they buy a truck. This will make them incredibly stale and predictable in the first 3-4 minutes until they can field a truck. (And probably another 1-2 minutes before they can field much in the way of units)
God, this so so wrong.
Everyone can make teching choices in first 1-2mins? And you call USF grende tech choice? As OKW you already have nades (juest get rid of 1 truck to unlock them/or make HQ upgrade like USF). Ambulance or weapon racks in first 1-2min? WUT?
Please tell me, how much fuel you need as USF to make first tech? Until that what you can do? Only RE or RF + grenades (if unlocked) and sweepers. You cant even plant mines.
As OKW you can get Kubel, Volks, SP and Raketen + grenades, mines, sweeper. Way more option than USF yet I dont see you raging on USF choices.
