Makes sense.

I wonder how the attack will go? The Asha'man seem pretty deadly, more so than the damane even. On the other hand, they don't expect the attack from the Seanchan and a large majority of their numbers is in the field now leaving the BT itself vulnerable. I could actually see the Black Tower potentially falling to the Seanchan.

Ofcourse, there are some problems I can see. Taim is likely a darkfriend and connected to the forsaken. Logain also states that Taim has some unique OP-techniques that he is teaching to his "favorites". And Taim's groupies form the majority of the people that are still in BT. It is possible that a seanchan attack would face some high-end AoL attacks and the like. Or potentially cross-gender links if the black ajah flees to Taim.

And even if the Seanchan win, Taim and his people being crushed might actually be quite beneficial to Rand. Might me amusing during the next scene if Tuon taunts Rand with the fall of BT, only to have Rand turn things around by explaining that Taim was a traitor, and thanking Tuon for dealing with him so that Rand did not need to.
