In my opinion, a confrontation between Shaidar Haran and Fain/Mordeth would have been fantastic. Then the buildup of the evil vs "anti-evil" showdown would have happened as alluded to in the series. Shaidar Haran( Avatar of the Dark One) fighting Fain/Mordeth(a force of its own). Would they destroy each other in a similar fashion as Shadar Logoth destroyed the Dark One's taint at the cleansing? Would one destroy the other? This would be better than finding the husk of Shaidar Haran at Moridin's feet, how did that happen??? If they killed each other or one triumphed, their storylines now feel like they have greater value. If Fain/Mordeth wins, then it could be killed by Mat without changing a thing. If Shaidar Haren won, we could have seen Cadsuane step up and show us why she is a legend. Maybe Cadsuane could have used an object from her paralis-net that we had not seen yet. One on one duels add relevance to character story-lines and give closure to the readers. Please post any other potential duels that could have been included in the final book that would have added only a couple of extra pages to the book, yet increased the depth and richness of a wonderfully crafted story that spanned decades in the making .
