Egwene's ending is so epic. Just reading what you guys are writing here is moving me :lol When she became the Flame of Tar Valon, something no one knew the origin of, I just screamed.
There is a lot to tie together and the Aes Sedai would have to use diplomacy instead of force, I agree on...
If the cycle is to repeat itself at some point the Aes Sedai has to become united again. It seems that union lasts for a long time as well. I doubt the two Towers unite in Cadsuane's time, but they probably don't start a war either.
As for how Cadsuane is as an Amyrlin I have to get further in...
