Actually, I see another way of solving the underpowered cavalry vs. overpowered archer problem with no changing any stats, but tweaking a little the gameplay.
I mean, look: cavalry supposed to scare enemies, destroy ranged from front and infantry from behind or flanks.
There's no problem with infantry vs cavalry fighting: great lance, even with nerfed to the ground cav, still outreach most melee weapons as it should do, and do great damage as it should do. And pikes are still destroying almost any cav with stopping it for a gangbang.
There's no real problem with dodging against ranged on a great distance cause most archers are more busy with enemy infantry that surely will slice them in pieces right after dealing with other infantry.
There's no problem with throwing damage on short distance cause throwing is supposed to do big damage on short distances.
There's no problem with cavalry vs crossbows, even it's crossbow that can oneshoot a simple horse at head, because engaged crossbowman with unloaded crossbow is forced to play as infantry or run, as it was in reality.
The problem is that archers mostly are not afraid of cavalry as they should be.Because engaged archer can run around and shoot impotent to hurt them the rider and horse to death in a few shots from 2-4 meters, or even few cm.
Engaged archers (mostly, if the rider's not a pro and the archer is not a noob) are not forced nor fighting melee, nor running for their lives.
What I suggest is forcing archers (because of their shooting speed at their run&shoot ability) fighting melee against cavalry (or run) if cavalry engaged archer.
There's a simple way of it. We got a system that gives
+1 shield skill if several shielders hold their shields close to each other.
Let archers get their some
-10 power draw skill
if there is a mounted enemy really close to them, if that's possible. That will put crossbowmen and archers on the same ground when countering cav, btw. Also, that will represent the disturbing feature of cavalry in behind.
Also, gieb rolling over ability for dehorsed horsemen.
