It seems that the new faction system is missing an important parameter for vassals organizing and joining the independence faction - threat level.
Under normal circumstances, a vassal of the emperor received the duchy or kingdom will not rebel immediately against his successor
in order to break away if, after the victory, he would be surrounded by enemies far more powerful than he.
There is no point Duke of Sinai to separate from HRE because immediately after the separation, he will receive the Jihad of Egypt from Fatimids and lose all holdings long before his possible victory.
Therefore, if stronger neighbors laid eyes on your lands sound policy requires to consider that only a presence in the strong сountry allows you to keep your possessions.
Similarly, I do not see the point in that German vassals to revolt against the German emperor as on just taken from the Golden Horde in the Polish territories with Tengri religion.
Horde completely cut them all in the next 10 years and this is virtually guaranteed.
The question is why joining the independence faction they ignore these threats.
Strictly speaking this also applies to Lower Autority factions.
Its clear why this to powerful dukes, but why the weak counts are adjoined to them if their independence from neighbor dukes guaranteed only by High level of Autority.
Should not they be contrary to strive to increase this Level and not lower it.
