I don't think you quite understand the need for good technique. Find a good teacher, I guarantee you, you won't regret it.
Because the more you practice, the better your technique has to be. And the better your technique is, the more can you practice, and the faster you will progress.
You implying that because John Bonham never had a formal lesson, then you shouldn't either, is an argument that I don't quite understand. Are you saying that you have the same talent that John Bonham ( or Dennis Chambers, for that matter) had?
I'm speaking from experience when I am giving you advice here, and am only trying to help.
Good luck again with your drumming!
