I agree with you Mellie, WR either outright ignores or has not considered (not sure which is worse) the fact that professional rugby influences the way that some clubs in the community play.
I also have yet to see any dangerous head shots in any games involving my club either involving our 1sts (Level 5), 2nds or 3rds, though it's not uncommon to see a tackle that attempts to stop the offload - which is something that started with the choke tackle at professional level. There has been times where I've noticed similarities between the way clubs in the Premiership play and clubs in the Premier Leagues (Midlands Premier for us) in the way backlines are organised etc. So it is certainly concerning that WR/RFU's aren't properly considering the influence professional rugby has.
I think there also needs to be a change of mindset in some corners of the community game. I've seen many comments on social media asking how they are now meant to stop the chance of an offload with the tackle height reduced. My thoughts would be that if an offload is a serious threat between a try being scored or not then perhaps it's a team's defensive ability needs to improve as well as tackling ability.
