That is not to criticise Wales' initiative. It has recognised that rugby, especially its showcase games, should be an entertaining spectacle, not a turgid affair that repels casual viewers.
But the outcome of previous increases in the value of a try suggests this is no straightforward matter. And devaluing penalties has proved a double-edged sword.
It makes it far less harmful to concede them, particularly on defence, a factor the Welsh address by making a penalty try worth an automatic eight points. That seems unlikely to prove a sufficient deterrent.
Understandably enough, All Blacks coach Steve Hansen favours the plan. In theory, it will encourage the type of game his side wants to play. To that end, he would make a try worth seven points.
Perhaps that is what it will take. There must be a tipping point when the value of a try will be sufficient to prompt a wholesale change of tactics.
Wales should be commended for at least trying to find it.
