One reason I came out here to look at the status of this game is that I've recently been reading a book by John Mosier called "Myths of the Great War".
Kinda curious if the developers of this game have read this book?
He makes a very interesting point about the armies of 1914, mainly the French, British and German ones. Basically, the Germans had switched their philosophy over to one that was much more based on firepower. The British and French were still more geared to a more Napoleonic type war with lines of infantry. That probably over-simplifies things, but I'm trying not to rewrite a 300+ page book.

Just a couple of examples. British and French infantry doctrine still stressed infantry using bayonets as where the final struggle would be decided. They also expected Rifle fire from infantry to be the main killer of infantry.
I think everyone knows of the French 75 as a key weapon. It was developed when they learned how to control recoil hydraulically. But what didn't know was that its maximum elevation was just 16 degrees. That would appear that the French still expected this gun to be used in the midst of an infantry battle in a more Napoleonic style.
Meanwhile, the Germans had instead used the new recoil technology to develop howitzers. Which were obviously more suited for the style of warfare that WWI turned out to be.
Add machine guns to the mix, and grenades, and mortars, and the Germans had a doctrine that was much closer to the modern war of firepower than the French and the British. The Germans were worried about getting firepower onto targets, and they had already moved away from the idea of infantry formations with rifles as a way to do this.
The Germans consistently had half as many casualties (or less) than the French and the British. And this isn't just when they were on defense. When the Germans attacked, they never just lined up their infantry for slaughter in the English way. The tactics typically credited to Luddendorf and thought to appear in 1918 had really been worked out by early 1915. The Germans moved their infantry in smaller groups, utilized cover, and concentrated on how to systematically reduce a defensive position by applications of firepower. The steady gains the Germans made in the Argonne Forrest battles of 1915 show these tactics.
Its a good book to read.
I was curious if the game team had seen it. It would appear to have a big impact on how units are rated in the game. A TOE chart could probably tell you the Germans had more howitzers, mortars, machine guns in a division than the French. But it may not tell you that the Germans had a much more modern doctrine on how to use these tools. From reading this book, it would appear that German units in 1914 and 1915 should have much greater offensive capabilities than any similar French or British unit.
