"It's got a lot more of a rugby league feel on it," Habana said at the Laureus World Sports Awards.
"If guys wanted to play rugby league, they'd go out and play rugby league," Habana said. "The essence of what rugby is about is something that I don't think any player or any supporter wants to see lost.
"There's something special about rugby ... your forwards pride themselves on the scrum and the line-out and your backs pride themselves on that contest against the opposition...
"As players, we just want to go out there and play this wonderful game we call rugby and hopefully they won't change what the essence of rugby is all about."
Well said, Bryan!
