Yes the cav based unit skills are so much downgraded compared to archery based unit skills. I mean in difficulty bannerlord all archers have aim bots and on the other side cav can't even do a charge for more than 4 kills with lances even outnumbering the enemies.
I know now why so many people like to play a fat archer on a horse, or a full Fiann party in the campaign.
I mean it's not a circle like archers beats infantry, infantry beat cav, cav beat archers, it's more like everyone beat cav.
