what about adding the posability to sit whit 2 people on a horse, its not weard to see 2 people on a horse, also we could make the horses being abel to carry stuf (if they carry stuf u cant put them in inventory)
There should be some sort of debuff though, or you can't do combat off the horse ... I'm just imagining 2 lancers with spears in opposite directions riding through the battlefield or guys flinging noob soldiers into the fray from horses xD
