I'm new to both this forum and my dojo, but I think that kata are immportant. You obviously wouldn't fight like that, but that is not really the point of kata. Kata are exagerated forms that were used as a way to pass down a system of knowledge in a peroid and place in time that the people practicing them were illaterate. Kata is inneftive if you try to use it in a fight, just like a screwdriver in ineffective if you are hanging a picture. If you are haning a picture need a hammer, if you're fighting you need fighting techinques. If you're putting shelves together, you need a screw driver, if you are demonstrating technique and working on a practice to improve form, balance, focus, spirit, ki, and endurance, then you need kata.
