i just noticed that you was wondering in the most replays that the players havent choose a commander even if the game reached already the midgame
the reason is pretty simple
in ef its much more important to react with your doctrin to the choosen doctrin of your enemy
so if you take too early your doctrin is mostly not that good
but dont get me wrong
it can work but you lost your flexibility and can't react on the chosen one of your enemy
The Soviets are unique in that their doctrinal selection does not entirely decide their route of gameplay.
With the Americans and the Panzer Elite, their Doctrinal selection is most likely made early-mid game and is used to fill stop gaps within the faction and supplement the faction with bonuses that are invariably used in gameplay
Ex. Using American Rangers to prevent early Vehicles Rushes in conjunction with Riflemen and help combat Grenadiers that Rifles can struggle against.
Ex. Using PE Hetzers as a better AT stopgap until Panthers
However with the Wehrmacht and the British, the Doctrinal selection is probably made early and used to only add onto the strengths of your faction selection, or increase the strength of an existing strategy.
Ex. Even though the Wehrmacht has access to Veteran Panthers as AT and plenty of Anti Infantry, the KT seals the deal to any game without ATG Spam
Ex. The British can already use Howitzers by default, however going RCA just amplifies your artillery advantage by improving range and broadening options.
The Soviets are quite reflexive throughout the entire gameplay and doctrinal choice is usually geared to how your enemy is playing.
