Whoever stated it, your right shotokan is strong with theres katas. You may notice what looks like pounding but after years of practice, your body adjusts and it no longer becomes "pounding". And also note while shotokan has strong katas with low stances; after you learn the basics, and become knowledgable with them, you have to learn to adjust your karate to for you and your body, without destroying the basics. This follows true for all styles.
