The Fuel to munitions to conversion comes way too early at only 3 command points, it's absurd.
It actualy comes when you need it, not a minute to soon, not a minute to late.
The idea behind CAS is sacrifice Tanks for air support, except at only 3CP it allows the Wehrmacht to just steam roll the early game with 5 LMG Grens, Flamer Pios and S mines. It's impossible for Allies to engage against such a munitions heavy army so early into the game.
Are we talking about 1v1? 2v2? Maybe more? 'Cause the situation you described it's more likely to happen in 1v1 games. But then let's not forget who is steamrolling whom. Untill those 3 CPs USF won't steamroll Ostheer? Penal troops spam won't steamroll grenadiers? And so on..... Ability allows for a convertion from 50 fuel into 120 amo. What can you do with 120 amo? Let's see... You can upgrade one and a half gren unit, or 2 pios... or ... should I give schrecks to that pzgren squad because a T34 will come pretty soon? Get the idea? The convertion just cover the necessity for Ostheer to have a well armed infantry (but still insufficient, let's not forget the med bunker, mines, etc, etc...). Insufficient because you can't have all upgrades you need so soon as you imply. And you still sacrifice alot of fuel while playing with the most expensive teching faction in game.
Yes you do sacrifice fuel for the munitions influx so it could be argued that you can counter the LMG Gren/S Mine/Flamer Pio spam with a fast T-70/Stuart/M15. But that can easily be countered by Panzer Shreks, Teller mines and infinite fausts. As for the late game Wehrmacht still has great non-doctrinal tanks with the Panther and Brumbar. Obviously not as potent as a Tiger but with all the strafes to compliment, it's more than enough.
Let's not forget that who is using alot of infantry in this game (even well-armed) will be strongly disadvanaged later because of 2 factors:
1. high squad-whiping probability;
2. high squad whiping probability increased even more in ostheer case because of number of models in squad.
The Fuel into Munitions conversation needs to either have it's efficient significantly reduced, or at the very least have the Command Point requirement increased from 3 to something much higher to prevent the early game abuse.
Strongly disagree, I don't see it as an abuse. Let's not forget that this ability appears in Ostruppen doctrine too, and nobody complained.
