Just got to say that I throw in my hat with the part that Clan stereotype is a aid to create interesting characters with relations with other characters. It can of course be done without such aid but it seems to me that as social predators an individual not possessing the necessary skills from the start for the kind of unlife a Clan (or coterie or sect) might force him into would soon end with the Final Death. Either by unknown foes, a displeased Sire or just getting caught by the sun or failing to get the blood needed. Exceptions can happen but they would be exceptions....
