The Game of Rugby has changed so much since I was a lad, to keep it more entertaining they have effectively changed the rules to make it faster, every game changes as mass substitutions come on the field, giving an unfair advantage to those teams with greater depth and breadth of reserve in players.
It's a competition the Haka announces that very fact, ok its an anachronism just like singing two Irish songs at the beginning of each game Amhran Na bhfiann (soldiers song) and Ireland's Call, no other team does that. lets leave what little tradition there is left in the game alone.
If you want to change the game for the better and make it more fair , restrict the number of substitutions.
