Warning: don't read below if you haven't finished the series.
Also for whoever had the Black Tower, maybe you could include a tech called "Asha'man guards" or something along those lines that puts Asha'man inside you towers to attack, making them an equal to bombard towers (as Taim did for the Black Tower).
And for whoever had the Kin (Ebou Dar, right?) you could have a UU channeler "Kinswoman", a cheap and weaker unit.
