Game design is so easy that nobody should be teaching it. If one needs to be told how to design a game then one shouldn't be a designer. It's mostly about knowing what's been released and trying to make something original. And if one wants to make a living one needs also to know what has been sold enough.
I don't think so--I can agree that one cannot teach another how to be creative, but they can give them tools that can be used to express their creativity. This holds true in all creative processes (including game design).
