I am in a very kata-centric dojo. We do other things too, but it always comes back to the kata. Aside from the basics like teaching stances, distribution of weight, transitions, combinations, kime, etc. the kata have so much in them.
One of my instructors made a statement in class a little while ago that over the past 8 years or so, teaching 4-5 hours a day to children and adults, he hadn't gone "outside" the kata to come up with combinations & partner drills & class "themes" to teach. This includes specialized sparring and jujitsu classes. Considering the huge variety I've seen in class, this statement is pretty amazing.
What's... not exactly discouraging, but somewhat disappointing, is how much you encounter this kind of point of view on kata. I've tried to point out in various threads (e.g. my reply to that post, here) that this is basically the wrong way to look at kata, and that it makes the mistake of demanding that the blueprint for a building itself create the building on its own. But you see this same conflation of distinct ideas over and over again. And this in spite of the now enormous literature on both practical bunkai and on realistic scenario training protocols for the TMAs... sigh...
