after watching the alta cast i likd the idea of being able to steal a % of players mounts that are left alone to return items back to town for them
could make like a role playing bandits and guards
just being able to fight a players mount they sent back home to drop off items if you catch them and damage them enough it will drop a % of them items “would not kill the mount” and the higher the mount lvl the less mats it drops it could only be attacked once per journey.
Personal twist (optional)
players could be paid to guard someones mount or if you see someone attacking a mount and defend it the owner could give something from the mount as thanks
