I'm unsure, to be honest.
At the end of the day, there isn't much of a difference between the two system and I don't find it to be more annoying if anything else: It's cool that your mounted units does no longer have canto and their typical high movement, so that they are at the same level of your foot unit, but It hinders them not having their weapon of choice(pegasus/wyvern knight-lance, axe knight-axe, etc...) and, even of It's minimum, I don't like that -1 in all the stats.
Plus, in Thracia, the good lance users in the game are mounted, while the two that can use lance in-door are terrible imo
