On many levels I agree. For years I hated forms. Even to this day I don't like to spend time on them when there are live bodies to work on. On the the other hand you should not judge systems that use them as training tools. They are used for solo conditioning and they also show what a person knows about speed, power, timing, accuracy, balance, relaxation and concentraition to name a few. Just because someone "wins" a tournement with a form doesn't mean they are any good at it.
Back in the days when the lions den achieved noteriety they sighted tai chi as a model used for relaxation. I believe Ken Shamrock also sighted Kenpo Karate as a small part of their mma style.
I also agree about resistence but, resistence is internal as well as external and some time needs to be spent without resistance as well. Why? Incorrect and misdirected use of power will take your balance and slow recovery time thus lending an oppertunity for attack.
Lastly I am an enormous fan of ufc, vale tudo, pride, muy tai, dog bros, pankration...
