The way Kyros has been built up to be an asskicking machine and only ever took one wound in the arena, it would be disappointing if he needed backup from his daughter who's performed a total of one (also completely ineffective) offensive maneuver.
Uh, you're joking right?
Kyro's was a badass in the Collesium days before Doflamingo showed up and Kyro's having to cut off his own leg in order to attack Doflamingo.
It wouldn't be disappointing that Kyros will need help in his next fight as he is now missing a leg.
