that's just realistic tho, Romans were routinely deploying gigantic armies with higher quality equipment and training than all their neighbours
not even the hellenistic monarchs of the east could match their ability to put out armies in the tens of thousands of heavily armoured infantry every single year, the only enemy that ever came close was Carthage

just look at how Romans absolutely shat all over Greek hoplites and phalanxes, as an example
