Now that Korean and Japanese are separated from the East Asian group, there is no reason to prevent Ming from becoming the cultural union. The current setting is weired.
If this makes Ming too powerful, adjustments can be done on Inward Perfection or local autonomy settings. (Although I feel not, as Ming lost her 135% technology advantage)
Also, I just finished the forming Qing achievement. Found 2 bugs:
1. Forming Manchu turns me into despotic monarchy yet I keep the Nomad unit type. I think someone already posted this.
2. After complete "Unite the Jurchen tribes" mission and form Manchu, there is another mission called "Unite the Manchu tribes". The code for this mission is actually start_the_conquest_of_ming_china. I think paradox forgot to fix the old localization for this mission.
