Looking at all the kata on YouTube, etc. All I can see is Oriental Dance, all the Kata has been changed and amended so much its a far distant cousin of the original form. Take Bassai, there are 36 official versions of the Kata, all claiming to be the correct one or the oldest one.
Shotokan and the JKA have formalised most of the Kata for competition and therefore unless you know what style they're almost identical, then you get the small dojo's that have been out of the loop so long their kata doesn't even look like the style they're supposed to be.
So I am of the opinion that Traditional Kata is for Traditional times. And like Ashihara Kancho and Ninomiya Kancho and others who've created modern Jissen Kata (seriously no sports kata is included as I think Freestyle Kata is .....) is the way forward for this day and age.
