It helps , players can use that to their advantage if he knows that the suicide killer has bad reputation. If the guy runs by a guard or just spawns close to them entering the map and get's spotted he is automaticly dead , it's not like players will level cap few more sneakers to just troll some traders. Wait wasn't this the case that you just could attack players with very bad karma in cities and not get punished ?
Rep never prevented anyone from suicidekilling another player.
If you have bad karma guards are supposed to kill you on sight. That's the point of this topic, if somebody kills few times players at gun runners he will eventually have bad karma so next time when he enters he will be insta dead by guards.
I think gunrunners shouldnt allow anyone having a gun unholstered. Its their place, their rules, someone having a minigun could be considered as a threat.
