I see this too often, "Ming can form Manchu". NO IT CAN'T OKAY? Ming can form China and that's it! Manchu can form Qing if the required territories are under control. Sorry, had to get that out of my system. It really bugs me when people think Ming can form Manchu.
Anyways, has anyone formed China? Does the flag change? Does anything else change besides the tax and faction removal?
