The history behind the design of OKW is bogus. The personnel quality of German formations in 44' were lower than those of 43', and those of 43' were lower than those of 42'. The Wehr peaked in 41' in this area.
The winter 1944 German elite divisions were generally a thin strip of veterans from earlier battles bolstered by the majority: green conscripts age 18-16 frequently. Generally 3 months of training or less prior to the Ardennes offensive. The damage caused by the offensive was mostly the result of strategic surprise and deception rather than formation quality.
Wouldn't that go against the whole point of the Oberkommando West? The units that are available to the OKW are supposed to represent the German Army in the late 40's(Battle hardened and having the best equipment in the war) which is evident by the fact that every unit the OKW has is high cost, but very effective; having a cheap conscript/penal like unit in the unit roster doesn't make any sense, and it would also throw the balance off by quite a bit. I don't think i'm alone in saying that the current balance is pretty damned great at the moment.
