So in 125, the Italian town of Fregellae launched a revolt after a proposal for granting them Latin rights was rejected. The Romans hastily sent the praetor Lucius Opimius with an army against the city and a local by the name of Numitorius opened the gates, allowing the Romans to completely raze the city to the ground.
Now it was widely believed at the time that the quick response and its severity (razing Fregellae to the ground) prevented a general revolt of the Italian allies similar to the Social War that would engulf Rome a few decades later following Drusus' assassination. So my question is, what if the Roman response was delayed enough to allow for the revolt to gain some traction and spiral out of control? Say the Romans are a little slower in responding and Numitorius doesn't open the gates so the city can hold out for a brief siege? What effects does a social war 30 years earlier (and, it should be stressed this is before the Marian reforms so Roman manpower is in an even worse straight than it was during the OTL Social War-it was pretty bad then too considering a lot of their manpower came from the Italian allies) have on Rome and the Mediterranean world?
