Some very good suggestions here. Personal, I´d like to see the following changes:
Make tiger and wolf only useable in Khitai, make new War Mare only useable in Dragonspine area. If you´re not going do that, please consider preventing their use in the capital cities (Old Tarantia, Khemi and Conarch).
Keep the auto dismount in the Khitai villages, but change the animation to the normal quick dismount animation.
