I seriously question this change and dunno if someone has a hidden prussian fetish at Paradox, but that breaks the game in many ways. It means the only real challenge is playing Austria or another german minor.
Yes, we absolutely have a prussian fetish here at Paradox
You have a ton of experience at the game, playing a major that is geared like prussia is isn't going to be super challenging, this is just the way it is. An AI can never come close to a really experienced player and without AI germany the balance in europe is lacking late game.
