I thought the same but then they would have stepped too much on byzantine shoes. It’s very clear in fact they didn’t want to give Romans a defensive identity.
I think their design is still historically inaccurate, they could do without a navy bonus and the scorpion’s one while cool works better with ancient Romans rather than medieval ones. Also I particularly dislike their eco bonus which feels kinda thrown in…
This is how I designed them before Ror was announced:
Bonuses:
Militia line units cost 60 food and 30 gold, skirmishers and spearmen lines cost gold instead of wood and food respectively
Blacksmith’s techs for infantry and armour upgrades for archers double their effect
Outposts can shoot arrows when garrisoning military units, units garrisoned in outposts heal 8x once herbal medicine is researched
Fortified walls and ballistics free (once reached castle ages)
Unique units:
Legionary (heavy infantry unit, upgrade from long swordsman, available in the imperial age from barracks, bonus against buildings)
Centurion (heavy cavalry unit, available from the castle in castle age, gets stronger the more units it kills in a row, bonus against infantry)
Unique techs:
Foederati (available in castle age, you can train unique units of your allies from the castle)
Fasti consulares (available in imperial age, wonders of your team generate food)
Team bonus: units behind a wall get 25% less damage
Missing techs:
Archery range: parthian tactics, heavy cavalry archer, arbalester, elephant archer, hand cannoneer
Barracks: supplies, squires, eagle warrior
Stable: paladin, hussar, battle elephant, steppe lancer, heavy camel rider
Siege workshop: siege ram, bombard cannon, armoured elephant
Blacksmith:
Dock: heavy demolition ship, cannon galleon
University: treadmill crane
Castle:
Monastery: ?
Economy: two man saw, guilds
They kept the idea of legionaries upgrade and double effect on armour but the rest is pretty different.
The theme I wanted to go is them having very strong units (they were still the strongest army in Europe until they could afford to pay it!) But a crippled eco to mimic the decay of the empire due to bankruptcy rather than them ever losing big battles. So a power spike in feudal and castle age while going down in imp.
I also wanted them to be very diverse to mirror reality like with the foederati tech and access to camel raiders because of Africa and arguably steppe lancers (the late Roman army was full of mercenaries, in the west it basically fell when there were no Roman troops but just a bunch of Germanic warriors).
I made this civ in collaboration with Robbylava and his version of it is on YouTube!
