I can appreciate those who come from a lineage that has preserved their kata unchanged for many generations feeling that they should stay unchanged. If you are learning the kata as the founder taught it, then there's little reason to change it.
How about those who are from a lineage that has changed the kata, whether recently or a few generations ago? The forms are not the original ones that was developed. Do you still teach the kata as learned? If you have no other frame of reference and are teaching it as you learned it, then you are doing it right. But what if you gain additional insight? Do you teach the kata as originally written or as you were originally taught?
Teaching it as written would constitute changing the kata from what you learned... So then do you change the kata from what you learned or keep the change from what was written?
