Trouble is, which is right for the Seleucids and other Hellenistic Kingdoms is not right for Carthage or Rome: you could defeat Roman or Punic armies and fleets ten times, and they would raise another one; you needed to conquer a lot of their provinces and wreck their treasury to make them ask for peace.
The Hellenistic Kingdoms, on the other hand, relied on the services of a relatively small group of Greek (culturally) military colonists. Only one serious defeat and they had to surrender; the survivors would be too badly needed to risk another battle!
