You will never hear me say that kata is not a training tool. The question is that if a martial art can be successful without kata practice, why does kata exist in some styles? Is it simply because of tradition? Is karate somehow more difficult to learn without kata practice?

Hanzou,
In many a FMA there are drills that are nothing more than a two man kata or form or what ever name one applies to them.
I have also see straight kata for FMA's as well.
Do I personally like them? Not really.
Do I teach them? Yes.
Why? I have seen some not able to get their hips into a strike until they did a simple Block / Strike Kata over and over and got better at it.
It is a tool that can be done alone to give repetition a chance to build upon. (* of course one can argue that if they practice wrong - different topic - different discussion *)
