Here's from my previous game. Spoiler : I could still expand more, but I already hade achieved my goal of getting the land of the Roman empire. Spoiler : I was able to pass all reforms without having to release countries or fighting against hordes. It seems to me that converting to protestant is the better path to getting authority (granted you have to vassalise or convert the electors in time). Also, horrible Asia: Spoiler : Oman is number 2 or 3 in technology.
