Franks power doesnt come from Mars, but he is good at making battle tactics (something he did get from Mars) and he is good with weapons, mostly his bow. As far as Piper, yes another camper has her power but over the course of her quest, she managed to make it stronger to the point of putting Gaea back to sleep and calling Jason back from the Underworld. Percy could have a special power, but because we havent seen any other kids of Poseidon, we may not know it is special. It could be his Ground Breaking move he did in The Last Olympian and The Son of Neptune. However, because Frank is a good tactician, I feel he would be better for a small group like the 7 while Annabeth would be better at using her smarts to lead an army of demigods (like the one required to take back the Doors of Death)
