I was thinking it might be nice if horses could act as pack mules rather than a mode of transportation. If you could load them with loot and give them the orders to "wait here" and "follow me" they would be much more useful. If on top of this they would run when attacked but return when you whistle they could be largely more useful.
As it stands now they are just a bad mode of transportation, only good for climbing mountains (lol). The lack of horseback combat and the fact that they are relatively slow makes them only a mediocre RP tool.
Anyone agree? Anyone heard any other good ideas?
