During the first Giant War, Dionysus and Hercules were the only demigods to fight along with the gods and they won. Why does the prophecy require 7 demigods?

Another thing is that, if Percy and Co. survive the Doors of Death, I think they'll resolve the Greek/Roman issue through a battle (Because peace missions have failed and that idiot Octavian is bloodthirsty). Do you guys have any other idea how the demigods will resolve the issue? Please Reply.
