What is the enhancement in mind? How should it look and feel?
I want you to make PvP better by making players that attack horses, damage the player sitting in horse.
Well, what's bad now, is that a player can easily run away from PvP with a horse.
When you try to hit a player sitting on a horse, you rarely damage him, that is very annoying for some players.
I want that when you hit a horse with a player sitting on it, it will hit him and do damage to him.
