This remind me an old saying said that a Taiji guy will spend 10 years inside their Taiji door without stepping out. In modern time, you won't find any swimmer who will spend 10 years on dry land without getting into water. To learn MA in your MA school and test what you have learned in local MMA gym is the best approach. If you have any problem in MMA gym, your teacher can help you to solve it. When you use this approach, you will not hear your students say, "My style doesn't use hook punch and roundhouse kick". Even if you don't teach hook punch and roundhouse kick, they will pick it up in MMA gym anyway.
