It depends how kata is taught. Keep an open mind regarding the practical uses of kata. Why would you think the early Okinawan karateka spent years learning just one kata if it had no practical use in real life fighting? :asian:Here is what my instructor said about kata.
He told us that they are not applicable in real life fighting, but they are the best preparation for it. We do not fight by using the kata that we learned, instead, we perfect our fighting form and motion through our kata.
Or sth like that, I can't explain it well, I hope you get his point. I'm a karate newbie btw
