Do all units of Parthia really need to have those things above their banners?



Add pics:
From what Mitch said, those are just the standards of Parthia... Does it really need to be carried by every units of Parthia in the game?
So in case of Rome, if there are 25 units, there must also be 25 eagles floating on each banner of roman units...
Isnt it better if those stuff only appears on general banner only?
Among all the factions in the game, they are the only one that has ornament on each banner of their units. Cant they just remove those completely?
They look more decent without those...
