I like trading horses, but Aserai lands needs some unique trade goods like spices, ivory, gems/jewels, camels, and gold. The lands of the south should be a traders paradise with grand bazaars with how important trade is to the culture. The resources of the area needs a serious overhaul and are pretty under whelming.
Camels - Also can we get these back, they should be the best pack animals in the game and available to buy. Running an Aserai caravan character with mules is not as immersive as having pack camels.
