You have no argument when you have to actually rely on the actual quotes in the books. You continue to miss the context some of these statements are made in as well ... note that Moiraine is defending her political position to Siuan when she makes this statement ...

Summoned

"Elaida insisted, Daughter, and queen or not, I doubt Morgase is a match for Elaida in a contest of wills. In any case, perhaps this time she did not wish to be. Elayne has potential. More than I have ever seen before. Already she shows progress. The Red sisters are swollen up like puff-fish with it. I don't think the girl leans to their way of thinking, but she is, young, and there is no telling. Even if they don't manage to bend her, it will make little difference. Elayne could well be the most powerful Aes Sedai in a thousand years, and it is the Red Ajah who found her. They have gained much status in the Hall from the girl."

"I have two young women with me in Fal Dara, Mother," Moiraine said. "Both from the Two Rivers, where the blood of Manetheren still runs strong, though they do not even remember there was once a land called Manetheren. The old blood sings, Mother, and it sings loudly in the Two Rivers. Egwene, a village girl, is at least as strong as Elayne. I have seen the Daughter-Heir, and I know. As for the other, Nynaeve was the Wisdom in their village, yet she is little more than a girl herself. It says something of her that the women of her village chose her Wisdom at her age. Once she gains conscious control of what she now does without knowing, she will be as strong as any in Tar Valon. With training, she will shine like a bonfire beside the candles of Elayne and Egwene. And there is no chance these two will choose the Red. They are amused by men, exasperated by them, but they do like them. They will easily counter whatever influence the Red Ajah gains in the White Tower from finding Elayne."

And let's face it Moiraine, especially early on isn't all that reliable... here are a few gems from her that are totally off base too...

Listen to the Wind

"The whole world will be overrun in five if we do not find those boys," Moiraine said simply. "The question worries me, also, but I have no answers. The Ways are closed, and there has not been an Aes Sedai powerful enough to Travel since the Time of Madness. Unless one of the Forsaken is loose – the Light send it is not so, yet or ever – there is still no one who can. In any case, I do not think all the Forsaken together could move a thousand Trollocs.

Look at that now all the Forsaken combined could not move 1000 Trollocs ... nor are any AS strong enough to Travel!

Remembrance of Dreams

“There has not been a Dreamwalker in Tar Valon for nearly a thousand years, but I could have tried.”

less than half of that actually.

The list of bad information or Moiraine's underestimating abilities goes on and on... falling back on an ambiguous quote from a "witness" who has been wrong on multiple occasions is laughable.
