I think its great to introduce and tweak game engine parameters. Thats how rugby evolves as a stretegy in the real world. It should never be a once of search for the Holy Grail and then you have the key for eternity.
Changing the parameters slightly during each off season would be best, then the really good teams will show their colours and adapt quicker than the rubbish teams.
