Surprisingly bad units

[Olaf The Great]

Are you kidding me???? These guys were the only ones that kept the Aedui from taking Bononia when i was transitioning to Polybian legions. They're the only Camillian unit (that i know of) that can stand up to the Gaesatae long enough for me to get skirmishers/cavalry behind them.

On that note, Now that i can't use them anymore, what Polybian Era Infantry can combat the Gaesatae? Are Polybian Triarii good enough or are the Polybian Principes better suited for the job?

I'd say Extraordinarii
