I remind you that there is a certain waygate in book 2 where no Aes Sedai is around.
I agree that Saidin being a big pool of clear Saidin is a bit meh, but still I would prefer to see the Eye of the World in some form.
What you mention, Rand smiting a Forsaken or setting part of the blight on fire as a huge army of Trollocs heading to Tarwin's Gap that was a day's walk away was retreating. Perhaps make a big curtain of Fire as the Shadowspawn run back.
An Accepted, 3 Wilders and Egwene and Nynaeve not at their strongest taking down a large army of Shadowspawn in an open field means that 5 Aes Sedai, even weak ones, could have lolololed the 100 soldiers or so that came for Logain. And it means that 7 Aes Sedai could repeat that without any of them dying and perhaps at more spectacular manner.
What I am trying to say is that suddenly an army of Trollocs becomes something 5 women can deal with - and yes 3 dying is good odds because it means that 8 women or 5 stronger women can do it too.
And again: OK, rule of cool. Or perhaps just 500 Shadow spawn out of 3000 or something passed the gap and the 10K was an exaggeration, perhaps by Darkfriends to break the moral of the people.
Why on open field? Why they waited from afternoon (when they gather) to night (when the battle happened) instead of going to the wall and helping them keep it?
Anyway, as far as Moraine goes:
