Well, okay. But they're a large part of many TMA schools. Doesn't this cede the point that forms are useless in combat, and by extension that TMAs do in fact teach useless, stylized techniques?
Not so much IME & HO. They're (forms) the encyclopedia of your "X" flavor of TMA. The same basics movements are repeated in different order, patterns, stances, sequences, etc... not to teach you to respond in "ABCD" fashion, but to teach your body how to respond with these techniques without it having to be in this stance, from this direction, etc...
I'm not going to use the same IF...THEN...ELSE statement I learned in college because the syntax & subsequent processing is different than the simple programs I started off writing. However, it laid the base to apply the IF...THEN...ELSE logic to any situation where it I need it to fit. If it doesn't fit, I have other choices to pull from. It's not static & wrote... it's fluid & dynamic.
