I have clocked about 200 hours now in this game and I have spent alot of time looking through the Empires_DB files (a very informative, organised and great resource if you are looking at in depth information) to find good compositions to beat the Roman armies with (on either difficult or very hard).
I noticed that while the Roman army evolves (which is cool), others evolve alot less (generally it becomes harder as the game progresses to beat Rome in a fight).
I think it would be really cool if other cultures have upgrade paths to their armies aswell (even if this might be slightly ahistorical because rome kicked everyone's asses and this never really happend). Most notably, there are no upgrade paths for Phalanx units, nation unique provincial units like the Sacred Band or the Spartan Phalanx (even though the latter are already awesome to begin with they could get a buff related to their cost or ranged defense on CIV3)
For reference here is a screenshot showing how roman troops and Carthaginian troops evolve:(https://gyazo.com/ba974d74ee3a0cbe721d6dcf81831bb5
I feel the only real downside to Roman troops is that all their front line units scale with cost which is a disadvantage they share with Sparta (for Rome Alae could theoretically fill this role).
How do other people feel about this and are there any plans for this down the line?
