My mistrust of TMA stems from way more than the forms, though I feel that forms are definitely part of the problem.
Think about that school you and I have been talking about. What if I were new to the martial arts and wanted to learn to defend myself and I joined that school? I would spend ample amounts of time and money learning sub par martial arts. I would earn a black sash, and walk around thinking I could defend myself with sloppy praying mantis boxing.
That's just not right.
That's why it pays to shop around until you find a good school.
That sort of thing doesn't happen in Bjj or Judo. In those arts, if you're not doing the real deal, none of the techniques are going to work. For example, if I'm trying to do a Kesa Gatame on someone much larger than me, I need to do it right, or I'm not going to be able to hold them down. If I'm trying to do a rear naked choke on someone, I need to do it right, or the person isn't going to get choked out. If I'm trying to do an Uchi Mata, if I don't do it right I'm not going to be able to throw them. All of that can be done in class against a fully resisting opponent. So I know almost instantly if I'm doing something wrong from the safety of my school. That is the advantage that Bjj and Judo has over TMAs.
In a good TMA school if you are not doing something properly you will know. If your kick is no good then it will not have power when you kick the pads and you will be corrected on it until it does and beyond. If you can't block properly and don't have good defences then attacks will get through. If you are practicing releases from holds and throws and you do them wrong they will not work. If you are in a bad school you may not know or care if you are doing it wrong.
