take succession for example, mongol like is that they gather a conference and elect one new khan, very "democratic", as long as you can live to the end.1. Yuan dynasty was part of the Mongol Empire. The Mongol Empire shrunk to the Yuan dynasty, having lost Golden Horde etc.
2. And what is 'Mongol like'? The rulers were always Mongols, reason enough.
3. Mongols did not ally with Ming, it was basically about Ligdan Khan and Nurhaci Khan and the Mongol tribes choose Nurhaci, because .. he appeased them .. anyway Ligdan was only nominally ruler, ruler of a small portion of Mongols in reality. He lost the favor.
that is not working for yuan.
btw: Ligdan is the last true mongol khan...quite disappointed see you credit him so little.
