Skipping technique part of class

There is a fundamental difference between a "formal class" and a "practice session"

I think many instructors try to fuse them both into one giant session.

Any technical instruction belongs in a formal class.

Warmups, Drills, sparring, all belong in a "practice session".

A formal class and a practice session have different goals.

You should devote your time to one or the other you shouldn't try to do both all at once.

If a person wants to focus on technical instruction, refine and learn new techiques then the entire class should be devoted to that.

If a person whats to "practice" and "work on" what they already know via drills and sparring then the entire time should be devoted to that.

No one class should do both at the same time
