I find it ahistorical and frustrating that the separatist rebels spawn with ballistae and onagers. It makes the entire rhythm of battle unfun, as I have to rush them with cavalry and basically suicide them trying to destroy it. I also cannot think of a single recorded instance of the historical Bagaudae using field artillery.
Anyhow, I love the new version but this is an un-lanced boil from vanilla that needs to go away.
