I don't really blame Sanderson. I think he probably would have done a better job had Harriet not rushed into the project. I don't even blame her for this, I understand why she felt as she felt. Ideally, I still believe she should have given Sanderson at least a year (or two, if he asked) to fully immerse himself in the series, and go to not one but a few consecutive rereads before he started working. The other mistake was to work with a (public) deadline, that sparked expectactions that Harriet then feared to disappoint. They should never have started publishing before Sanderson finished writing. They were not Jordan (and even he had problems with the larger picture, and that showed in the late series), and they deprive themselves of what writer and editor normally do, that is stepping back to look at the whole and polish it. They repeated the same mistake Jordan has made in the late series, when he built WH to climax with the Cleansing, without advancing the other storylines to that point first. Though very different in tone (and story), TOM has the very same kind of structural problems as COT, only even more important.
