I fully agree, the nerf was good to heavy cav, but I do much the same and pick off people in the back who are fighting teammates, and very often they swing through the now dead corpse with a sword or pike and hit my horses legs for massive crippling damage.. to avoid this you basically have to avoid helping teammates, yet I think cavalry should be encouraged to play in a support role for their melee lines. Removing the friendly fire leg bonus would give back the incentive to be supportive.
