Turn it around, Indirik. Say no one ever gave you a bigger estate just because you changed your class to Cavalier. But then, when your Lord notices that you've changed your subclass to Diplomat, they reduce your estate size, and tell you if you want your bigger estate back, you'd better change back to Cavalier as soon as the timeout expires.
You make it as if there always was an implied threat. It's not necessarily the case. It could very well be "I noticed you decided to become a diplomat, that's great! Since you can't recruit so many troops now, I'll redirect some of your revenues to your peers so they can recruit more."
