At least UFC judges wont be as biased as say K-1 judges. It was so obvious. Im usually am watching K-1 Max every year. And every event when a Japanese Fighter fights a non Japanese Fighter. Plenty of times you watch the fight, and you go "for sure that non japanese guy won 2-1." And the judges know this, but they want to give the Japanese guy another chance so they just say it was a draw. And then they go to the sudden death round. Ive seen it happen too often where one fighter will overwhelmingly beat the japanese guy short of knocking him down, but somehow it still ends up in a draw. While the japanese guy has to land a couple of punches and he will steal the decision. It was just a blantant abuse of the sudden death rule. Even if you feel you already have a winner, you will just say draw just to see 1 more round of that fight.
K-1 was my main combat event, but I stopped watching it when it became clear that the event was getting as suspicious and crooked as the PRIDE events near the end of its demise. You might not see that kind of abuse in the UFC, but you will certainly see lots of sudden death rounds in fights because its easier that way, it also provides another round on an entertaining fight, even if the people had a good idea on who won 2/3 already.
Of course im not a fan of it if its permanent, but if its only temporary for the flyweight tourny, then I have no problems. But again it just goes around the original problem and masks it, which is putting more specific judging criteria so they can get it more right and accurately.
