In my view, you seem to make some very large general assumptions about what you "can" and cannot" do on a consistent basis at your level. Well that's the beauty of this medium where everyone with a keyboard and internet access is equal. You are obviously entitled to your experience and your opinion based on that experience. Perhaps when you have more than a few years of experience, and maybe when you make black, your conclusions may change. I know mine did. That's why there is a Tiger and a Dragon symbolically represented in the Chinese arts, and American kenpo where Mr. Parker often spoke of the differences even in his manuals. Good luck in your experiences tiger.
