Well this "feature" has been enhanced enough that it now does more than what was intended.
Unless you intended to buff cavalry even more?
The second (and worst!) is that stupid "auto-stun the archer if you get within 5 feet of them." I've been 3 feet behind a building or a tree that the cavalry galloped past and gotten the "auto-stun" because I was behind there with my bow drawn waiting to shoot them in the back as they drove by. REDUCE THE AUTO-STUN AREA OF EFFECT. Hell, you can't even blame it on the wind of their passing. I'm behind a WALL!
You shouldn't have your draw interrupted because a horse rode by a wall or tree you are hiding behind. Their horse fat doesn't flow around the obstacles!
