i dont believe i edited any stats to do with the barbarians (this was a long time ago, i dont remember), but baring in mind the only reason the western empire fell was because it was way softer than it was in romes golden age, and in the imperial era the germans were only ever good in their numbers and if they set up ambushes, when rome fell, it was because their troops were soft, their land was hardly guarded, and tactics had changed due to all of the steppe tribes invading from the east
