Advantages of granting land to your own dynasty members:- +5 opinion modifier -- negligible IMO
- Higher 'Dynasty Score' -- if you do not care about dynasty score, ignore this. -- negligible IMO
- (in the future) potential ability to press their claims *even if* you are not their de jure liege. To clarify this, here is the scenario: (Johnny being of your own dynasty)
a. Johnny has a claim on a county/duchy/kingdom
b. Johnny has NO HOLDINGS in your realm at all
c. You invite Johnny to your court, start a war with your CB pressing Johnny's claim.
d. You win the war, Johnny is now the proud owner of the claimed county/duchy/kingdom.
d. If you are (at least) one tier above Johnny's new position, you are now his liege. (If it was a county and you are a Duke, he is now your vassal count; if it was a duchy and you are a king, he is now your vassal duke; not sure if it works the same way with kingdoms but I guess it should be, of course you need to be an Emperor/Empress)
Now in the above scenario, if Johnny was NOT of your dynasty, he would have shaked your hand, said thank you, perhaps gifted a bottle of wine with his business card and took off.
I can see having a gigantic dynasty with claims to known world and beyond could be a strategic asset; having said that, as I do not intend on steamrolling map I am perfectly fine with (fabricating claims) or (going with the 50% rule to chew slowly).
Therefore none of the 3 above is a huge advantage for me.
Now let's take a look at the
Disadvantages of granting land to your own dynasty members:- You simply cannot use the method of stealthily eradicating (assassinate) their entire dynasty to reclaim all their holdings if it is your own dynasty
Well, short list but that is enough for me.
To put it bluntly, with the above game style, I use people as containers, their purpose is to contain holding(s) as long as their service is required; and once it is no longer necessary, they should leave without creating a scene. (preferably via death by natural causes as it sounds cool). Yes I know it sounds bad but I am a very loving and caring person in modern times
BTW, before coming up with this Machiavellist method I tried to be a good family man:
1) granting counties to cousin/auntie/uncles etc;
2) duchies to brothers.
Then I heartbreakingly experienced that
1) once you give a county they want the whole duchy;
2) when you give duchy, they demand other counties in it. You say give all counties and be done with it? No,
3) then they ask for the second king title "you don't use it bro; no head can take two crowns!". I say, "I use them as rings, 20 fingers on me, you fool!".
4) As an additional 'great dynasty benefit' extended dynasty members also provide free assassinations (assassinating you and your heir apparent)
How can they assassinate the great leader of their own dynasty who [brag]conquered many counts, dukes and kings; wisely never spent a dime on fighting heretics; ruled in justice as long as it suited his own agenda; never delayed punishing any wrongdoings (to himself or his heirs)[/brag]. If they (AI relatives) don't act honorably why should the player do so....
In many cases 80+ year old NEW NOBLE will conveniently die without producing heirs therefore you take it all back without spending any money/dishonorable_act_penalty_point on them; you just repeat the process.
If they get crazy enough to attempt bringing a kid in this crazy medieval world; when they are 80+ and gone next year; is it a sin to send that child to angels; to say the least we are saving that child's soul from great suffering ahead.
Now that I think about it; actually we should get both prestige and piety points for each soul we save, plus opinion boost with the Pope.
EDIT - so with the above setup, once you (perhaps painfully - if you start big) get to the point of 1 vassal = 1 demesne system, only heaven lies ahead.
EDIT - oh BTW, vassal levies = MAX; church levies = MAX; so that even if they ALL rebel; owing to the fact that they do NOT rebel at the same time; you use A's troops to put down B's rebellion; then use C's troops to put down A. Try never using your own troops, and keep them as reserves at all times. This way you will always be able to respond in case many many crazy servants (some call vassals) rebel at the same time.
Another benefit of employing service of "one man dynasties" as your vassals: if push comes to shove you can quickly assaseliminate 3-4 of them quickly to take out 30K troops in the field; this is cheaper than fighting them with your troops [paying with levies] or mercs [paying with much much more gold than 50 per head].
