I hope that Egwene's Tower will have a lot to do with giving the death blow to the sul'dam/damane system, once word that the Empress and all the sul'dam are channelers.

Personally, even though I would have condemned Rand if he balefired them, a part of the reader in me that just likes a good story with large stakes, would have cracked up if he balefired the Seanchan. But that would have caused more chaos as the nations under Seanchan control fell apart with no central authority.

That being said, the main problem I have with them overall is cultural, rather than the status and dehumanization of a tiny minority of their population. They may be badass, but I'd like to see order come from a system stemming from a representative community similar to the White Tower. That seems closest to the world government that existed during the Age of Legends and the system Artur Hawkwing had in place.
