Don't you think it's also an overall nerf to light horses too ? HP is nice and all, but losing maneuver for that aint gonna cut it.
Arabian only loses 1 speed, which is oK for the extra 19 hp & 4 body armor.
(Not that it stops the shit from getting 1 hit but hey)
I already rolled my 15/24 lance cav build so idgaf bout this speed loss, just gief more armor, yo yo.
