Hetairos, the unique calvary of Poseidon, should carry a lance rather than a sword.
As a depiction of the companion calvary of Alexander the Great, they aesthetically look fantastic, but historically carried a lance rather than a sword. As it currently stands in AOM retold, they feel redundant recycling the exact same sword and attack animation as the Hippeus. I feel that equipping the Hetairos with a lance would make them appear far more unique and would appropriately set them apart from the hippeus.
Contrast this with Hades’ unique archer versus the standard Greek Toxote: they look and feel remarkably different.
Small change with big impact, just my opinion. Also, maybe consider reducing their gold cost, lol.
