Minamoto no Yoshitsune + Cao Cao (Best fort combo, both have great bonuses against barbarians)
Belisarius + Minamoto no Yoshitsune or Cao Cao or Boudica
Belisarius skill reduces defence, and the secondary skill hits after that dealing increased damage.
No specific talents needed, but if you are cavalry spec, try to get a full cavalry rally.
