I think your points are quite accurate, and you highlight exactly *why* Sanderson's works are often "almost" novels. Works written with Sanderson's speed will, by necessity, be lacking the finished and polished appearance of a carefully written novel. Of course, taking one's time doesn't ensure that a book is good - A Misery of Words Dance with Dragons is proof enough of that - but Sanderson's works would almost certainly be improved as a result.

I still find him a fun writer, but I think he does have the ability to be a much better writer because he has interesting ideas that, if improved from a stylistic standpoint, could make really good books. As it is, they're "almost" good.
