Before the patch, it was like:
-Horse Archery skill was reducing the wpf of archery and
throwing (just like power throw and power draw skills, do reduce throwing and archery wpf)
Now it is:
-Horse Archery skill reduces wpf of archery and
crossbow (no drawbacks to throwing wpf now)
It means a nerf to Horse Crossbowmen/women and a buff to Horse Throwers
Come on, I'm not the one being from NA
