Yeah, pretty much any scene with Cadsuane. She takes the whole "I know everything" that Aes Sedai have, even when acting from a point of ignorance to a whole new level. And her general arrogance is just too much.
I think by the end the sheer number of characters just got too much (for me) and I found myself less interested in reading what the lesser characters were up to. It was just filler in between the good bits and I found myself impatient to get back to the main story.
