I disagree with the Beyonder and Molecule Man being placed so high and labeled pre-retcon. They were never actually that powerful, they only appeared that way. The Beyonder's powers were deconstructed and he turned out to be somewhat of a hoax. He became a much lesser super being, and his previous super feats were nothing more than his imagination. It was later shown that the Beyonder was actually a Cosmic Cube.
Since the Beyonder and Molecule Man merged together to form a new Cosmic Cube, shouldn't that be the power level they are placed at?
" Including MMA as a choice is pretty much the same as having the option of all of the above... "
Wrong. Just as Jeet kune do is not "all of the above". Both MMA and JKD borrow techniques from other styles but they don't necessarily master every style. In fact most MMA fighters master Brazilian Jiu jitsu?Kickboxing/wrestling and never delve into Dim Mak or Pakua Chang etc. "
No, it's not wrong. It's called mixed because it can include techniques and styles from any martial art. Lyoto Machida has trained in Shotokan Karate and Sumo and Anderson Silva has trained in Capoeira and Aikido. They are still considered mixed martial artists. The reason you see so many Muay Thai kickboxers, BJJ practitioners, wrestlers, boxers etc. is because it has been shown to be the most effective fighting style in the cage.
Saying you would choose MMA is like having someone ask if you could have chocolate, strawberry, or vanilla ice cream, which one would you choose and answering all of them.
