For UFC
- Many of the title fights are scrapped because of injuries.
- No direct competitor, like PRIDE FC.
- UFC doesn't allow knees to the head on the ground, or soccer kicks/headstomps. It's safer but makes the fight boring.
- No immediate rematches of split decision title fights; Jon Jones vs. Gustaffason should have happened quickly because it was too close to call.
- Dana White has hurt the sport along with improved it.
Boxing
- Everyone wants to see the heavyweights, but there are like 5 titles for them now just to be the Undisputed Champion. So there is a ton of politics, and you can lose the belt if you don't fight the #1 challenger.
- 12 rounds have made it safe, but boring when in the old days it was 15 rounds
- Expensive PPVS
- Alot of ducking by fighters
Not to mention that in a real fight, if there were no rounds, no one would punch because the longer the fight goes on the more likely you would break your hand. Which is why they don't like fighters to use palm strikes, its more effective. Not to mention the action would be much slower, because with 5 mins rounds in UFC, you know you can get a breather after the 5 mins where a real fight without rounds means you have to pace yourself.
