not agree... as dv8r say, is a strategy to decide hard tackling or normal, or easy... think that if the other team have hard tackling will see more cards and is more possile to have a penalty for you...
maybe one different suggestion in this way, is;
1 med pack, if you don't have cards,
1 med pack, if you do not injurie a player of the other team (we know that, sometimes injuries occurs, and ..no card for the other so,,,)
I am really not sure about that, but, if there is a change, this change don't have to affect the strategy teams, and "delete" it. ..cos nobody will use hard tackling at the end with that...
