The way it currently is, if a Duke or Count is indepedent and they have a "mother" title, they pledge allegiance. Now I like this on some levels. For instance, I saw Germany wracked with Civil War, only to eventually pull back together. The downside of this though, is that break-away vassals will always end up coming back. Why not have them pledging allegiance be based on their power? A strong Duke that successfully breaks off should continue to stay broken off, unless badly beaten up and "power" reduced. Thoughts?
