Well I meant to complicate the process a bit.
Now you can just rebel instantly and only if you don't get the land you asked for. How about that you can MAKE UP the reason for what you rebel.
Spread the word of the king's incapability to rule. Influence the lords to follow you or to start their own rebellions (from 1 kingdom, many counties arise xD). Bribe/Influence the lord to follow YOUR rebellion and serve YOU afterwards.
Plan your rebellion by giving your land instructions that they FOLLOW
you and ONLY
you, if you fail to give orders to a castle they will not be your land when the rebelion start but you can conquer it and ask for it when asking for independence. The more land you have and the more of them you give instructions to follow you, increases the risk that King will find out about your plot and react.
He may banish you, by taking your lands back if you're in middle of somewhere, or ask politely to stop if he has good relation with you.
• In case you're IN a castle/town when he decides to take your lands, you get to keep that land as you're still there (Auto rebellion starts? Maybe? Or your servants try to seize you? Or you get 50% of army fighting other 50%? So your loyals against king's loyals... idk, depending on what u want to do).
Oh my god, my imagination is crazy.. -_-
I am thinking too much.
lel.
This is just what I meant by adding option to rebel
