Throwing horses!?
Are you all daft??
(The trick to horse archery is to stop, shoot, or move slowly and shoot, then run. It might help to try a similar strategy as horse thrower.)
No, thats NOT the trick, you can fire accurately with bows at full gallop, just aim up and right. Once you forget about using the crosshair, the accuracy is decent and you dont get shot.
But horse throwing IS very limited, by ammo and range, but close with your enemy and hold ur mouse button, since u dont loose accuracy, and release at enemy horsemen when they are totally convinced they are gonna lance you, and try to always cut them off, as in their horses nose hits the side of your horse, and rears up, thats always a good time to drop a javelin in their face.
