If you took away the OOB and replaced it with generic strength points it would ruin the game. If you don't like rotating units in and out of the line (completely historical) than maybe WW1 operations aren't for you.
Not sure what it would remove other than the bother. I had very few circumstances where
I couldn't get things balanced the way I wanted. I suppose some story is lost, if you don't
know that that's the 3/34/II or something, but honestly, all the fiddling made the story
largely disappear anyhow. Only when I backed up and looked from on high did I get a
good view of what was going on.
It's completely historical to track water, fuel, different types of ammo, spare parts, ect.
But I sure wouldn't want to play it.
The entire story would be lost. No one would even buy it.
