MMa has lost something that was special IMO.
Although I have enjoyed MMA throughout the years, I feel that MMA has lost a unique trait that was initally started from it's first conception. Let the Best fighters show their styles/mad skills and test their crafts against each without having to place fighters in different weight classes. This should be done every 4 years to determine once and for all who is the Grand Champion/the Baddest MotherFucker on the Planet Pound-4-Pound.
Take for example the first UFC Champion, Royce Gracie who weighed in at 176 lbs. The man took on all comers, some were larger than C-C-C and Gracie still reigned supreme!
Don't get me wrong. I do enjoy all the mad skills, the ground and pound, the submission holds (I still don't know why Ken Shamrock didn't win the WWE Heavyweight Title, it must have been fixed IMO), and I don't mind the mounted position as long as it's a short ride. But what made me start to watch and enjoy MMA was watching a scrawny opponent win over a vastly (my new word for some reason here on FN) larger opponent.
Now take the Spider Silva. He is a fine athlete with proven skills.... darn duty calls, BBL.
