So, as we know the Roman ninjas and other such similar nonsense was by no means true to the historical narrative of RTW, but what fantasy units/ features did we like and want back regardless?
I for one will vouch for screeching women, nothing was as entertaining or relieving in dealing with some screaming wenches from the cold heart of Germania to take your mind off of your last defeat in the Teutoberg forest. Perhaps include them as a 0-1 unit, I'd hate to see the AI spam them, and after seeing some of the more suspicious AI stacks in previous titles I wouldn't put it past them.
