I think that a deserving general should get the special ability and that the requirements should be pretty high for him to get the trait. This would encourage people to groom their heirs (too bad you can't choose the heir, thanks CA.) to try to gain these abilities.

It could be cool too if a non heir general picked it up and made him prone to rebelling against the current leader. I have yet to have anything like this happen in any of my games though they have just left the faction while wandering through the wilderness before.

Are the EB team going to be changing the way rebellion works? Make it more like BI for instance? I remember MTW where they had civil wars....pretty cool...but I have read in the forums this cannot be recreated in M2TW so what are the alternatives?
