Traditionally, the german army during the early stages of ww2, was superior to the allied forces and this should have been reflected in giving them a +1 in anti-tank. (Veteran german units in the later part, especially ss units, were tough nuts to crackzen!) I know the two leaders being present is supposed to account for that to reflect their combined arms superiority. I still think it is a shortcoming (well, I guess with the editor this is moot).
I know that the game is nearing completion, but right along this point, I think there should have been representation of airborne and SS troops (Germany fielded 500,000 SS combat troops).
I also think it is a misrepresentation that strategic bombers can bomb units (as RAF's sole bomber unit can do).
Actually, french armor was better than the germans during the start of ww2 but they did not organize into effective battlegroups and when they did later, they simply got tore up by the luftwaffe. I think this latter part is reflected correctly in the french's stats in SC.
