The Seanchan aren't so likely to strike again at the WT soon. They got new damane, and they'll get Travelling soon, but the raid wasn't as succesful as could be hoped, and they probably realized it's not because AS have been few and far between in all the nations they conquered that there isn't a whole lot of them at the WT. The fact is the AS were also able to strike back (while leashed ones can't be forced to make weapons with the Power.. a mystery that Mat and his AS solved for them in KOD by revealing in front of DWG officers that it's a matter of their lives being in danger... if the DWG didn't report this, they will after the raid when the response of the Tower during the battle will be carefully analyzed- and this has a major implication: if Tuon stays away from the Tower, the AS won't come on the offensive, because they can't - the Empress will now know how Hawkwing was really able to conquer the whole continent while the Tower did nothing, whyso few AS have opposed the Seanchan advance so far... The real threat to deal with, the real priority, is now the Asha'man and Rand, as those can and have attacked the Seanchan. It's not the AS the Seanchan will plan to attack next, it's the BT... Yulan's plan involved maps of two areas in KOD - Brandon seems to have cheated because of the book split so that the two strikes Yulan planned were not discussed at the same time. Jordan's original idea for Yulan's plan was most likely that in phase 1 the Seanchan hoped to steal Travelling and the "AS weapon" and use this to strike at the BT very soon after. Brandon probably chose to alter this a bit so the plans for the Asha'man were not brought up until TOM. Originally, the ending of TOM wasn't happening in AMOL a whole lot after the strike on the WT - 5-10 chapters after maybe? We'll see after TOM how many chapters cover the post-TGS timeline), and Egwene's stunt with the san'angreal will be a deterrent for a while at least - we don't even know if the Seanchan know what angreal/san'angreal are - or if they'll believe some rare AS dwarf the strength of the strongest damane - at least the Empress now has an idea of how much resources she'll have to commit to finish off the Tower, and that's a lot, perhaps the choice between committing most of her damane, many armies and halting the Return to strike at the WT - with the possibility her losses will be so high the rest of the campaign will be doomed (the Empress too is fully aware the LB is about to start...), or go on the way Hawkwing built his Empire, by securing all the nations before she isolates and assieges the Tower again (and with Travelling it will be near impossible... they will have to settle for destruction, or capture of all AS).
