How about if both teams are forced back 10m at the play the ball, and if the dummy half is caught in possession ("sacked") before reaching the advantage line, then it is a changeover to the defending team?
I think this would see less dummy half runs, as a team would not want to risk losing possession if the dummy half was gang tackled back over the advantage line. Then both teams would be on an equal footing wrt distance from the play the ball.
