They were stupid examples, and Nynaeve and Elayne had a better understanding of what Moghedian and co were capable of, because they could actually access the ability that made them capable! Give some examples that are not completely ridiculous, of what she could tell them that is both useful and from which they can actually work out something they can do about it?

Because that would be CURRENT and RELEVANT information! It is going on now, not 3,000 years ago. Oh, wait, that was just an example, right? You are not REALLY talking about Iran, and so you should not be criticized for making an irrelevant digression. What POSSIBLE good could they extrapolate from knowledge of what a Forsaken did in a completely different world, a totally different setting in which they have no context for understanding her actions or her agenda, concerning a man who has been dead for 3,000 years? They would learn how she WOULD HAVE laid a trap, for LTT if he were still alive, and living in an AoL-comparable society. That knowledge would be about as useful to them as it would be for a medieval person to understand the political tactics Al Gore used to try to steal the 2000 election. Way to go. If the middle ages SUDDENLY turned into 20th century USA, they might know how to go about blocking a lawsuit to recount the votes from a couple of counties. It tells them nothing of how Al Gore will try to hunt them down in the middle ages with his magical superpowers that the people from the 20th century would not understand.
