For me I’d like to see the both ‘try/no try’ call and 6 again removed from the game. I’d like to see penalties given for players deliberately moving of the mark & off loading after the ref has called held as opposed to being let off. Also any player that stops a game by slowing it down before the ptb by holding their head should go off for a mandatory 5mins for a HIA.
Also think the offside & obstruction rules need tweaking as some good tries have been chalked off for incidents that have had no impact on teams defending when they’ve simply made a poor read or defensive play.
