Logging systems cause performance lag, as it would have to pull up hundreds of pages worth of actions. Take Mlogs for example, baseline it logs like 4 categories of actions and each Category has a sub category of like 8 different things like , Kills,damage,commands,chat and so on. Point is, the best logging system we have FOR NOW is the console. It's currently set in the rules that noone may be killed unless in a simulation or event or schedules executions. Therefore we can use common sense to determine, "Was there an event going on? Was there a scheduled execution? Was this in the sim room? Was Sim Active during this time?" Im pretty certain the chat can log timestamps if you enabled it and OR you can record and use that as evidence. Yes not everyone can record, so the console and chat timestamps can help because the console DOES say who killed who with what weapon.
All in all, a logging system is nice to have and great quality of life, but at the same time there is an alternative method, like doing a bit of investigation and asking for additional information. you can ask Person 1, his reasoning for killing person 2 and almost in any scenario its not a good reason and therefore be arrested for RDM.
other than console no it doesn't.
-1 Isn't needed at all.
