About the officer pool, i don't think there is such stress. Currently, there is plenty of designed leaders that players never see in their games, because :
- it is expensive in EP (-4)
- it is still random to get it even when you activated the Option
- the pools are big, and so few leaders are on the map at the start of each scenarios.
- As pointed in this thread, the CP capacity of the main Army/Corps stacks is so huge that you don't need so many new leaders
So considering that it is a pitty that so many originally designed leaders (who now many of them have even a nice leader graphic from Jack54

) could never be seen in the games at all, the next patch changes planed are :
- EP cost reduced to -2EP
- a regular random event will offer sometimes a free leader from the pool during the game (even if players don't activated the More leader Option).
- few leaders more are on the map at the start of the Grand and middle campaign (in fact, the leaders which biography said that they were already commanding at least a brigade are placed historically where they were).
- a reduction of the 2* and 3* leaders' CP
There is also something which could be good about leaders' micro-management, especially to counter-balance the low activation chance of Red leader which block its button : to implement that a leader can form a division even if he is inactive (i think AJE does like that, isn't it ? i hope PhilThib or Pocus could confirm that we could set it in a simple way for RUS).
