What if the Huns were destroyed before Attila was born? How would his campaigns go? Would he re-unite the Huns?
Err how can he be born if his people are destroyed prior to that :/
No Hunnic Empire means a heavily fractured group of barbarians. Normally, the Huns absorbed all of these tribes but without Hunnic unification, these tribes would just fight each other and there would be more strings to pull for the Romans, especially in the east.
