I think a change in that a golden try only then stops it. If a field goal is scored the remaining time/the other team has the chance reply via a field goal too. If at the end of 10 mins extra time ( ie without a golden try) then a draw is called. BUT BUT when a winner in extra time (golden try) that team gets.... One and half premiership points while the losing golden try teams gets half a point. This means 2 premiership points were allocated/won. This gives the losing side a small reward/winning side a reward BUT not two points. This will play out on the table better when the final eight is finalized. The one and a half point and half point shows the true nature of the game ie it was very close, the winning side does not deserve the FULL two points.
Also with having half points opens up interesting ideas of say, a nines comp (3 rounds) with the winner getting 2 points R/U getting 1 point and semi finalist half point each which will make for true style competition..
