To be honest I'm wondering if the kick to touch is a bit harsh for things like offside, a tap seems adequate punishment for me, and have the kick/penalty attempt for more serious offences (spear/high tackles for example).

According to Ben Thaler, time cannot be stopped for a drop out until all of the team who is kicking the drop out is behind the line...

If this is the actual rule then that needs changing immediately...

this is why the aussies kick our butt unfit players not lasting the 80 min

It doesn't now. Or do you mean, a two-man tackle, where one of them falls off of lets go before the tackle is completed shouldn't count as a two-man tackle?

Id like to see any kick from your own half that goes dead result in the ball being handed over where it was kicked, there is no skill involved in players deliberately kicking the ball dead with the aim of conceding a 20m restart and the ball in the air nonsense should be stopped if a kick to touch is over the line by metres and somebody leaps from the field of play over the touchline and bats it back in it should be classed as being out
