Must try a little harder

I'm tickled pink that England beat Australia in the quarter-finals of the Rugby World Cup, but it does once again highlight the problem of the way the result of a game is decided. I think we would all agree that the object in rugby is to score tries - so why is it then that the side who scored the only try of the game lost? I think it is high time to consider doing away with the penalty kick at goal. Take a quick tap penalty or kick for touch and get the resulting line-out by all means, but let's have the game decided on tries, eh?
