I quit watching MMA basically for 3 reasons:

1. Came to realize after watching many fights that a LOT has to do with just sheer luck. Swinging punches at each other, one connects and the other drops and goes into fetal position (very unmanly). Then the winner is declared the greatest fighter in the world...

Technically, from a striking point of view it is just horrible. Grapplers throwing hands basically.

2. The lack of knowledge of both MMA fighters and fans.
They think they understand other styles because they call themselves MMA'ers. But in reality MMA just stands for Mediocre Mixture of Arts
Anytime you hear an MMA fighter talk about boxing, you realize they have absolutely no clue about the complexities of both technique and strategies of boxing. Baffling ignorance.
Just watch YouTube clips of (obvious self-taught) MMA-coaches teaching boxing technique. They just have no clue but that doesn't stop them in confidently talking absolute rubbish.

3. Forced tough-guy act
There is a massive inferiority complex. (I actually heared an MMA'er say about boxers "they think they are better than us"
They always want to convince and remember everyone how tough they are.
Boxers show post-surgery photo's just to show all went well
MMA'ers (both man and women) just lóve taking pictures to show open wounds and every severe injury just to show how 'tough' they are. No other athlete does this.
