Most infantry players shun the fact that lancers have Insta-kill, unblockable offensive capablities, which I would understand, were it not becouse Couching was never Overpowered in MM, It was simply so that most Infantry players had recieved little or no training on how to effectivly counter Cavalry.
And about the Unblockable, Instant kill Attack, You can draw parallels to firing a musket. Of course, it has less accuaracy and Is not instant kill on long range, But then again, in order to couch someone, you need to get within a meter of the fellow.
