It is a pretty high armour rating, only a handful of infantry units (all of them lvl5) gets higher than that.
Also, take into account that they will get a better 2nd weapon lethality than similar units (due to them being armed with longswords) so you're going to face a pretty good unit even out of phalanx.
They represent the seleucid "agema" cavalry, basically a companion unit recruited from the persian nobility.Other than that, I highly agree with the Persian Heavies getting a buff to
being close to Hetairoi stats.
Iphicratean spears should be halfway between hoplite and phalangite in lethality.That reminds me, will Iphicratean Hoplites have higher lethalities, as their
pikes are shorter, so they can thrust harder?
I didn't quote your stats because I'm developing a system from which all units will take their values, part of it is available in the latest release EDU.
