Successor game rules, draft one.

[Ibn-Khaldun]

I can say my opinion about that retinue matter..

If you start roleplaying a pious character and all of the sudden you receive a pagan magician then I guess you really want him to be removed because this would affect your RP. The game shouldn't control our RP that way.

Edit: I'll get back to other points soon..

Seizing armies: 5(b) "A Noble may not move his avatar onto an army owned by a Noble from outside his feudal chain unless both Nobles agree to the move beforehand."

I do like the option of seizing Captain led armies though.

fleets: fleets that do not start a turn in a port or with a noble are there for chancellor to move around.
