In league it is 6 for a converted try and two for a penalty and I don't see teams infringing too often. But yes when it was 4 points for a try in rugby - it used to be stink. Your tactics were to get into opposition territory and hope like hell you won a penalty. Get Foxy to kick it over and then repeat.
I have a number of pet peeves about rugby - but the point system isn't one of them.
