After Li Jue joined the war between Parthia and Rome, it became a complete mess. The Romans had gotten accustomed to adapting to local conditions and never thought another nation would assist Parthia. The only potential threat they anticipated, the Hunnic cavalry, never appeared; instead, another army did.
The current Roman equipment is entirely designed to counter Light Cavalry. To be precise, their current military structure is enough to vex most Light Cavalry, including the elite White Horse Soldiers.
Yet, it all came to nothing; Rome wasn't prepared to confront Heavy Cavalry this time. If they had known such a formidable Tugi Cavalry would join the war, they certainly would have brought along Teutonic Throwing Axemen, Phalanx Shield Snatchers, temporary caltrops, and such.
