There's no reason to think she would say anything. She didn't say anything and her lack of evidence can't be used as evidence. Besides, I have better things to do than degrade Nynaeve's strength, but that doesn't mean the Forsaken can't be shifted around. Maybe Graendal is only one step higher than Moghedien, and Semirhage is the powerful one. We just don't know. There must be fifty possible combinations which allow for Nynaeve to be average Forsaken strength. We only know that Lanfear is at the top and Moghedien at the bottom. The other three can be anywhere.



I don't think this is relevant. Everyone who's ever spoken of Sharina has described her strength as incredible. They don't really care about what's there and what isn't there yet. If Sheriam does, she's the exception to the rule.



Well there's no proof of that, really, but it's as good a guess as any.

Of course the other possibility is that Semirhage hid her potential with an inverted weave when she met Rand, and hasn't unravelled it yet. The others can't do it, so they don't know how strong she is.
