It's amazing how amateur these referee's are, as MMA has evolved and continues to evolve we still have not seen a change in Judging / Reffing.
Hopefully as this past generation of fighters enter retirement, many of them will pursue judging, reffing fights. Example : Shaolin Ribeiro
It's obvious many of these Referee's are old Relics of the 70-80's, example: Cecil Peoples a legend in his own mind who has no business being an official in any aspect of MMA.
Mario Yamasaki is f'n terrible ...guy operates in slow motion ...most likely due to his obsession with throwing up hearts.
Dan Mirglisomeshit is a human highlight reel of mistakes.
Herb Dean -- was a good ref but when he started taking money under the table it showed in his inconsistencies of reffing fights.
Big John -- old relic who chooses to be the "authority" and tends to think the fight is about him rather then the fighters....he's decent and has been around for a long time but he's not perfect by any means.
Marc Goddard has shown as of late to be the best referee in the business, he understands everything that's going on at all times and makes the right calls.
