what i would really like is some way to either instigate fights between NPC's, or even trick guards into killing someone.
as it is, if a non-hostile guard witnesses someone attack you, they automatically jump in on their side, even if they didnt witness how it started.
just now in Tarant, i beat a guy unconscious with a mace, and then ended combat without killing him and walked off. i waited for him to wake up and start limping after me, and then lead him over to a guard. the guard wasnt hostile to me at all, but once the guy limped over and tried to punch me, the guard instantly started attacking me
i wish the guards would treat you and NPC's the same way
