Conversions are boring too. I think it has too much bearing on a game.
While I don't like it the way it is being done now I think there's potential in the idea.
How about this. In stead of opting for the conversion you can have a full set of six starting from the 20m line. Play as normal, meaning all players are available, kicks are allowed and the opposition can score. If the opposition is tiring this might be put a dagger in the heart, or if you're way behind it has the potential to get you back into a game.
Tell me that O'Connors sideline kick to win Origin was boring.
Or Cronin's faultless kicking in impossible wind in the 81 gf.
Or Matt Ridge kicking goals from halfway.
Or Churchill from the sideline with a broken arm.
Or the stories of Dally M kicking from 60m out.
Or the skills that Hazem, JT and Halligan brought to the sport.
Or even watching the stupid prance of Soward, Inu's silly grin or Piggy's salute.
The whole point of a try is to close that phase of play, let the defence regroup, let the fans have a leak or scratch their stones, and start again. With a kickoff at halfway.
Besides, conversions are not mandatory as it is - teams can elect to go straight to the kickoff. That they don't means the quick break - gathered thoughts, quick drink - is quite valuable in the game. Would rather see players get their act together with a quick break than see them get burned out because the fans think goal kicks are boring.
Besides, League has the balance between tries and place kicks right. AFL and Basketball have the same scoring method used ad nauseum throughout the game. Union relies on kicks too much. League rewards the skills of attack and defence AS WELL as the skills of ball control with hand and foot.
