Krayt alone is strong enough to hold off Bane, with Wyyrlok adding support Bane gets wtfpwned. Or if Wyyrlok fights Zannah with Talon and Nihl she is done. She can't possibly take as many Sith, that were stronger marginally than the Tython strike team. There are too many and Zannah isn't skilled enough to fight them all off, Bane will be having the fight of his life with Krayt and he would be in no position to help really.
