I've nothing against changing rules, I'd like some changed back to the way they were, like less interchange, a full 10 metres, proper play-the-ball.
Most fans want to see proper 10 metres & play-the-balls. The issue isn't the rules - some games are fine, others are dodgy - so it's actually about the consistency of their enforcement.
There's 2 key problems with the way the game is played at the moment: attacking teams rely far too much on simple dummy half runs & defences rely on too much wrestling & gang tackles. Why? Because coaches know that the rules of the game disproportionately reward those tactics.
The NRL know this is a problem but their response has been to tweak around the edges - banning certain tackling styles or enforcing different rules more strongly. It hasn't worked because the advantage is still too great. Even if the NRL does what you want & enforces those rules, the reward for boring safe tactics is still too high.
The only valid response is to change the rules to favour creativity and variety in attack. A general 40 metre kick advantage is not solely about kicking. Because it creates defensive gaps, it encourages teams to pass the ball more. That means more side to side passing, more line breaks, more kick & recovers. If teams stick to simply dummy half runs only they will score less points than the teams that use a variety of options. If teams gang tackle, they risk allow their opposition to exploit the gaps. The game is faster without the need for any more interchanges. It brings the element of fatigue back into the game.
Let's be honest - unless there's a major rule change to address these problems, this boring play-it-safe style of rugby league will remain the status quo for sometime to come.
