* Have a system to differenciate between gankers and rangers. A criminal scent would be left for the murder of someone without a scent linked back to them. If there was a murder done to someone who already had a murder scent attached to the homestead, then no criminal scent left. It is just too difficult to keep the peace when the criminals actually have the advantage when they can summon rangers who keep the peace. If you want to be a criminal, then make it harder to get to the Sherrif.
* Have a scent level system installed. Just like real life, there severity of the crime determines the punishment. This would link back to being able to summon kill.
* Restrict the distance a town bell is created by someone who does not own a homestead nearby. The ability to run around with a character who has the town bell skill and just hostile take over settlements seems a bit too overpowered. For instance, a town bell is able to be place next to a small plot of land that may be right next to someone. Once the town bell is placed, it creates a radius that actually covers the other settlements without some sort of permission of the other nearby settlements. Coupled with the issue of the town bell not being able to be destroyed, makes it overpowered.
