I think the books have taken a perceptable dive since his wife took over as his editor ca. book 6. IMO, that when they really started getting uneven. He clearly doesn't know what his readers care about, or give a damn if he does. We get major plot points in throwaway comments and hundreds of pages of arms crossed under breasts, braid pulling, sniffing, shawl-fringe groping, and the constant steady fall of previously distinct female personalities into one irritable collective with many bodies.
Also, I have hated Perrin since book four.
The latest really took the cake, though. I think they had one real major plot point in the whole mess. After the conclusion of the previous I really had hope. Sure the whole book only took place over a span of about ten days, but THINGS HAPPENED.
