From what I can se 300-400 years ago, most systems had maybe a dozen forms at the most. Now many oF those same systems have 30,40 or even 100 or more forms. I think each generation adds forms to the system, and afetr a wile, they really start to pile up. That's why I always look for the original system when I can. There is less material to learn.

I'd say the concentration on forms is a modern thing to replace the barbaric act of fighting.........................................T hen came the UFC
