I've lost a little interest mainly because of how Dana White has been running things by giving out title shots to losers, adding women on PPVs, etc. I still watch roughly the same number of fights per year though probably.
This is why I'm watching less. I have no issue with having more events but the UFC has made it clear they are leaning down the WWE path rather than the sport path. From what I understand that is purely a money decision, their market research shows that is what the majority of fans want but it is exactly the opposite of what I want to see.
