These forums are a wonderful resource for Law changers. World Rugby and Rugbyrefs: WR should use these forums. Imagine when WR decide on some new Laws, they then put it out to us to investigate, delve and comment. Not to change the intent of the new Law, that is an already given by WR, but to identify issues, inconsistencies and weak language.
WR wouldn't have to engage, it could also disregard what it felt to be irrelevant, but it would have access to some highly experienced and often forensically inclined rugby brains. WR could wait and see what we come up with before putting the final version out there. WR doesn't need to respond or even engage, it would just take on board what it felt was useful and hone the new Laws accordingly.
