Isn't Jon Snow Lor'themar 2.0 since Lor'themar has not wanted the throne for nearly 10 years and everyone around him tells him to keep it. Rommath even at one point hinted he should be warchief.
Also can we take Saurfang's words about following rogues at face value? If so we have the two most incompetent rogues to ever grace Azeroth and outland. And I have seen some very incompetent rogues in human hands. Being found out by a warrior is something else.
