Part of the reason I’d decided upon doing Rand/Egwene first was because I knew that this book—Perrin’s sequence in particular—was going to be the trickiest of the four major viewpoint sequences. Of the four leads, I felt Perrin was one of those who needed the most growth. In fact, he had as much to grow as Rand did—but in more subtle ways. Rand’s descent was a result of the multitude of forces pushing against him, bearing him down, threating to crush him. He was brought to the point where he was because his personality issues were magnified a hundred times over by the extreme circumstances of his life. He cracked while trying desperately to find the right thing to do.
Perrin was different. He had major hangups that he consistently refused to confront, and in many ways was the farthest of the main characters from where he needed to be. Rand’s transformation was more dramatic, but Perrin’s was just as necessary.
It should be noted that I felt, both from the notes and my own readings of the series, that Mat was basically where Robert Jordan wanted him to be. This remains true even after I re-looked at Mat and tried to fix my interpretation of him. That doesn’t mean that Mat is finished as a character, just that he was where Mr. Jordan wanted him for the Last Battle. Mat was going to have another series all his own after the main group of books, and some of his character progress was saved for those. (Note that those books are not going to be written.)
Egwene had a small amount of development left to do, but was mostly there. In The Gathering Storm , she faced the most critical challenges of her career, but Robert Jordan had brought her to the point where she needed to be in Knife of Dreams , and in the notes for A Memory of Light he had indicated specifically how she was to progress. It was mostly a matter of using the confrontations in the White Tower to manifest things she had already learned, and to show once and for all the person she had become.
As for the other characters, Elayne was where she needed to be, but Avi was not. (She had a great deal of growth left to her.) Nynaeve had reached the peak of her development, in my opinion, as had Min. At least this is my read on it, which is reflected in my interpretations of the various arcs of the characters.
