I love both. I love revolving belts. I love dominant champions.
The thing with dominant champs is the value they add to the belt. Winning a belt that has swapped hands for 5 years will never carry the same weight as taking it from a champion that has held it for 5 years. In closing, revolving belts are good for the fans and the entertainment value. But as far as pure sporting reasons are concerned, a dominant champ is a very healthy thing.
