Yes dev you made some changes to the way horses heal, but still not good enough. Why is it, that horses heal up so much faster then humans ?
I suggest you make it so horses heal up just like humans: Super slow if not healed by a human. If healed by a human, then ofc it takes the usual 20+ min to get back hp according to the skill of the healer.
This could be done with the same person who heals humans, or even better by the person who train horses or with the animal lore skills.
And ad to it, i would love to see horses break bones just like humans. In the case of a broken bone, the horse will ofc move slower
More realistic and a way to remove a little more stupid magic from the game
