I mean i'm not going to blame staff entirely for the actions of the people who use this platform to roleplay; Most of the murderhoboing [CAs] and [MAs] exist from a time before most of the current ST were even apart of the system; and these pieces of lore persist because (Besides the murderhoboing aspect) they have provided roleplay that is consistently beyond the quality of the average lotc roleplay experience. I think what would be best in that instance is to just make an ST ruling which bars new submissions and any rewrites from having a mechanic which encourages murderhoboing; or direct murder in general to achieve a particular goal. (Yes we can have dark magic that plays on other themes than murder)
Regarding the main point of the the post; I agree that murder needs to be a tool used on special occasion outside of raids and warclaims. But in order to have any type of real rule-based server change we would require staff intervention and a complete rewrite to our rule-system. These things take time and given that this topic has been brought up multiple times there's likely not a novel solution any of our staff can think of that is also simple to implement. Most proposed ideas say things along the lines of "We should have lives" "We should make a death application to be reviewed to tell us if our chars are pk'd based on the rp" but all boil down to adding more staff bloat; which staff as a general concept never like. So, the only solution is to manipulate RP culture by convincing most characters not to kill and/ or create severe IRP penalties for people who kill. Or to discover that needle in the haystack rule which is both simple and effective at reducing the amount of murders which occur on lotc whilst also improving the general RP quality surrounding the death.
One idea I have would be to require a "tell" emotes which indicates to the person you are RPing with that your character has some type of malevolent or unnatural intent towards their character, but have yet to spot your character or initiate their plan. Something along the lines of; *A band of 3 brigands walk along the road surveying every knook and cranny for something, or perhaps someone; though as they draw closer they have yet to see [Persona name of target]*. If they continue to rp as they were and ignore the tell emote they are then liable for all RP which ensues after; but if they rp running away or hiding from the murderous threat then they are not liable to be murdered so long as they avoid the conflict.
