In my games I usually have very low grade kings and only a few good generals that I let do all the fighting. It seems to me that raising uber princes is the best way to get good generals and governors. So I've got a few questions about getting good generals & governors (heirs in particular)

1. for a governor to get the steward or builder virtues, does he have to be in his province when you build stuff?

2. does building certain buildings give your governor specific vices/virtues?

3. can your heirs get steward and builder virtues by being in provinces when something is built?

4. for getting virtues like specialist attacker and defender, do I just have to win battles with few losses on my side?

5. are there ways to improve your general's accumen, other then titles?

6. are the command stars of your maturing heirs determined by your ruler's influence or by his own command stars? What else effects this?

7. if your first heir is inferior to those who come after him, what is the best way of "disposing" of him?
