Yeah, btw you can't hope nothing more with akontistai and gundi palta, than become meatshields and annoyances in the battlefield, they are untrained peasants and urban poors pressed for providing good numbers in battle, and soak up enemy missiles (hence their cheap costs and upkeep).

If you want to see how effective the javelins are, use peltastai, they are my primary killers most of the early to middle part in my Hellenistic faction campaigns...
