Canister Shot

[oz_wwjd]

In your experience how effective is the "canister shot"" artillery option? I've had some truely epic moments with it,such as when 3 of my demi-cannons unloaded into the flank of the enemy's troops causing huge losses and a mass rout,but sometimes they seem to want to fire over the enemy's heads instead of hitting them, Nothing is most frustrating than seeing a volley of canister going flying over the advancing enemy,when hitting them could have made all the difference..
