Moghedien has had her BA moments for sure, but I have trouble giving her credit because she's always been a bit of a coward. When the chips are stacked against her, she is nothing. Not to mention, I think Birgette and even Liandrin (gag) in those scenes show more courage then Moghedien ever will. Granted, Liandrin's attempt was a little more dumb than courageous, but still...

Anyways, my fav moment has got to be when Rand cleanses saidin. I know this wasn't a direct battle or anything (it was more going on all around him), but the fact that he had the stones to even try that is pretty amazing. It's scary to think what Rand and Nynaeve could have done with all that power besides cleansing saidin.
