How historical is the Romans not having artillery prior to Marian Reforms? The Romans use artillery against Numantia(133BC), Carthage(146BC) and Corinth(146BC). I was assuming that the EB team was sticking to historical accuracy and I was assuming that they would have included at least some type of artillery(light scorpions,ballistae) after the Polybian Reforms and added more advanced types with the Marians? Anyway this could be amended in a easy and concise way?

What are your views on this guys? I mean even Carthage gets artillery earlier than the Romans.

PS: This is not EB bashing just a wonder if the great EB team made a oversight which has yet to be rectified even in EB 1.2.
