Another option is to have random surprise 'celebrity judges' that are announced as names on the card.
These appearances could be fighters, ex-fighters, movie stars, sports stars - anyone really that is known by the fans (obviously lots of cross-promotion $$$s potential; if the Rock has a new movie coming out for instance he could be a card's surprise celebrity judge, or Jack Black etc)
Publicly advertise the celebrity judge concept for each event as an added marketing ploy. Introduce them at the event, have them walk around the octagon or say a few words with Rogan about what they'll be looking for etc... then at the end of any fight that goes the distance, they could have a dramatic decision where the celeb reads their cards aloud (drumroll, etc) like thumbs up thumbs down Caesar moment or something. Interviews after about why they made the decisions.
This way it makes the judging fun, and the criteria could change and flow from card to card. Fighters would take better warning to finish their fights as to 'never leave it in the hands of the judges', but if it does go to the card's celebrity judge, its anyone game but no one can be upset at the decision because they know its already fucked, lol Their fault for not finishing and leaving it in the hands of Conan O'Brien etc
That, or PRIDE rules.
