Yeah, that doesn't really pick up fully until book 11, unfortunately: but when it does, it does so with a vengence.
As
@Demetrios1453 alides to, without spoilers...in Robert Jordan's original "I think I can do this in 3 novels outline, the end of the first projected novel ended up being the climax of The Dragon Revorn, while the projected end of book 2 ended up being that of Winter's Heart. So, technically, arc wise Winters Heart is the fairly decisive conclusion of Act II, and books 10-14 were what Jordan thought he could do in a third novel.
Outlines were not his strong suit.
