Still i don't understand why the Gallic Junkers need an id for their own. Nothing stops a normal Junker to stay in Gallia as long as he wants.
But why was the Guard ID converted to something new then? The players who had the Guard ID before (and were happy with it and did good rpg) are in trouble now.
And i think, there IS a difference between Guard and nonguard. A normal Junker cares more about his private stuff and would not mind fleeing from a fight where is friend is about to die to save his own life. (I experienced that ingame as well) He doesn't care that much about Junker politics and is more or less a not so important Member of the Junker Guild. A Junker Guard cares more about the Junkers in general and protects them if anywhere possible. He's from the "hard core" of the Guild and plays a more important role for them.
At least that's my understanding of Junkers, and Junker Guard.
