The heavy horsebowmen of TC and BK do work, about 10x better than they used to. They may or may not be as efficent as they should be or could be, but it is a step in the right direction. You need 20+ in order to really see the effects. They don't work alone but if you have them on a flank, they do very well in causing alot of damage (because of the bow and lance) before they lose many forces.
