The swing arc for the polearm hitting animations differs quite a lot when executed mounted (excessively obtuse arc) and when executed on foot (more natural acute).
When swinging a polearm on horseback the model twists excessively obtaining an ugly texture squeeze and an unrealistic anatomical pose).
