Here's what I don't see as such a big deal, you say that you don't like the idea of two of the same class being related and one having done the stuff already that the younger one is going through, no says that you have to make two of the same class how you go about building your family tree is completely up to you and really it doesn't make a WHOLE lot of sense unless you made a guardian and want to go back and try playing a sentinenl, but then again you don't really have to add them to the family tree either. Anyways, all this means little to me since I only play one character and that "in practice" is who I am in the game.
