6 players allowed on the bench, but maintain the number of interchanges per game.
HIA the main reason. Teams can be quickly down a number of players through no fault of their own...
If someone gets taken off for HIA, sit them out for the game. Takes care of the player but also would stop the rorting of the free HIA interchange.
Allows for a mix of forwards and some attacking player options on the bench. So the spectacle should at least be maintained, if not improved. Loads of people talk of “fatigue” in the game improving the game quality and this is maintained, or at least counter-balanced by more attacking player options that can come on.
