Fetchers appear to be out as the new trial breakdown laws bring considerable changes to the structure of the 15-man game.
The new laws have been introduced by World Rugby and will be trialled in various competitions around the world during the next six months.
It is supposed to bring a cleaner game and make it more entertaining but there are concerns it is moving more towards rugby league and taking away one of the unique points of the game - it is always a contest for possession.
The laws were used in club rugby in Dunedin and did not appear to make a huge impact on the game but at the next level up - where everyone is bigger and faster - they may be more noticeable.
Millar said after Otago's win over Southland in Invercargill on Sunday the new laws make the approach to the breakdown a significant change for players.
``It is a completely different mindset. It can be accidentally sometimes when you lose your feet. But that is the detriment of the team now. It is an easy three points for the opposition,'' he said.
``You see a lot of players not committing to the rucks now on defence. It takes away the whole cleanout aspect of the ruck.
``It is just such a big change. I think we will take a couple of weeks to get used it. We need to cut down a few of those first-half penalties we gave away. I think it is just as much fun, creates a lot of offloads and zero people in the ruck.
``It keeps the ball alive. That is not a bad thing and it will be awesome when we get back to Forsyth [Barr Stadium].''
Teams can carry the ball into the breakdown and those in support effectively seal the ball off so as to continue to the next phase.
The only danger is if sides go off their feet in supporting the ball carrier, something Otago was guilty of a few times in the game against Southland on Sunday.
Teams also find if they have no hope of getting the ball at the breakdown - which often happens - they simply get in a line of defence right across the field.
Millar said that happened a few times on Sunday.
``The defence fans out a bit and it is about staying in line and getting back to your feet, not lying on your back on the bottom of the ruck.''
Otago coach Cory Brown said on Sunday the referees and players were going to take a while to adjust but the key was players staying on their feet.
Hawke's Bay captain Ash Dixon told Sky television on Saturday the new laws were creating a hybrid game of rugby league and touch.
The laws will be robustly reviewed early next year at the end of the trial and then a decision made on whether to run a global trial next year.
