Out of precisely fifty cavalry units (not counting generals, elephants, or chariots, but counting camels and duplicate units), two have a unit count other than 27—Scythian Noble Women, with 18, and Desert Cavalry, with 40. Unless somebody can come up with anything that sets these two units apart from the 96% of cavalry that have a unit size of 27, I think they should be changed (but with no changing of their other stats).

It's sorta similar with long_pike units, with two important (but related) differences: there are only five units in the game with long pikes, and the percentage that has the "standard" unit size is therefore a lot lower (80%). Also, the Pontic pikemen were also clearly intended to be inferior (-110 cost, -80 upkeep, and same building level), but their +3 shield makes them strictly superior to ordinary Phalanx Pikemen if their number is raised (and even if you remove that, they'd still be strictly better than Greek pikemen due to the cost). Based on this, I think that a unit size of 40 is in keeping with the developers' intent.
