Overall I think it's a great move; marketed right it should help increase exposure to the competition and sport overall. The final playoff event to determine a winner might be controversial, but from a fan and excitement perspective it's a great move. Surfing, with the WSL, went through the exact same format change a few years ago, where instead of a winner being determined solely based on points accumulated throughout the year, they instead switched to a finals day, where the top 5 surfers in each mens and womens surf heats, 5 against 4, winner against 3, winner against 2, and then the final. Lots of long-time supporters don't like it, but again, from an excitement/entertainment perspective, especially in getting outsiders to come to the sport and easily understand it, it was a smart move. Hopefully it works out for World Rugby.
