What do you think about the AFL and their rules committee, tinkering and changing the game? Has this effected the game over the years? IF you are happy with rule changes, should we have more?

Personally, I can't stand the AFL constantly changing the rules, experimenting in the preseason with no kicking backwards, minimum length of a kick etc. Why do we want to constantly change the greatest game in the world? I really can't see the point and it only confuses players, umpires and supporters.
