Hi, i want to give a suggestion about the nobles switching faction mechanics. After about 30hours of gameplay (on realistic mode) i've got the whole map conquered by southern imperium. I've joined the empire as a mercenary first and vassal then, but i've noticed that after a faction take the upper hand against another, nobles start to massively switch faction. Of course with more nobles and more armies the faction can easily conquer more and more in a snowball effect that allows the conquest of the whole map in less than 400 game days.
My suggestion is to limit a lot this mechanic, for example asking the senate to vote to accept or not a noble who's switching side, or not accepting nobles if they have a bad relation with faction leader. Furthermore i've noticed that during the campaign a couple of faction switched not just once, but even three or four times, going from empire to khuzait, then back to empire and so on. It would be nice if those who betrayed once can be rejected the second time they try to be restored into faction.
