I would like the game to be: first - consistent with historical reality, secondly - I think it will make the game more attractive, and thirdly - it will make the game much more difficult
Therefore, I have set up 5 stages of my project:
1. correction of all erroneous or inaccurate dates of battles, operations and campaigns and their duration in time
2. corrected dates of all, coefficients and cost of some units (for now German, unfortunately it took me the most time), in addition to removing some and adding other
3. correction of the specialization and creation of a resonable system of specialization development for the Waffen SS
4. changed the emblem of the Wehrmacht to the Greek cross on a black background, consistent with the historical reality
5. minor corrections - eg. correct names of commanders etc.
EDIT. 5a. complex tests of improved content
6. collect all these files into one and create a Mod for the game (EDIT. after the release of the new, big Patch for OoB, of course)
I've already completed stages 1-5 (mostly
), there was remained the last point but the most important, I'm just reading the manual "how to create your own Mod for OoB"... 
I regret very much, but because of my poor skills of modding, I limited myself to the player-controlled factions, while the AI-controlled factions were left unchanged
I think I did a titanic work with German troops in the units.csv file, next I will deal with Japanese and US Army on PTO
The British and Soviets only after the release of subsequent DLCs, similarly the correction of US troops on ETO
I will try to describe all the major (and minor, too) changes in several subsequent posts
