Victim has ship rebuy of some millions, cargo potentially in millions. Versus an armed assassin who has perhaps about 5k tops in lost ammunition cost.
You want the guy who would have lost millions, to lose more millions. Perfect. This will empty Open and you'll have no one but other armed bandits to hunt. Who can shoot back and ACTUALLY put your own ship and rebuy on the line.
If you can't see that frontier have some work to do in this respect, you aren't paying attention.
It isn't just about traders. Traders just play a really tiny role as they are already rare and harmless in open. The only "traders" I kill are freighters from PP factions to deny fortifying a system. Other than that the usualy c-logger I encounter are fighter ships who are more than capable to defend themselves. Elite Anacondas with railguns and torpedos. Deadly Pythons with lasers and hammers. Deadly and Dangerous FDLs, FAS, Clippers and more with multicannonns and plasmas.
My favourite case is when someone engages on ME and then suddenly notices "Oh damn, this guy is really good." and then logs when I was about to blow him up for annoying me near a station. If you you thinnk that a player who chooses to play open and fires to first show for a PvP fight shouldn't be punished from combat logging then you are lost. I doubt that you think that but there is a possibility.
Open includes PvP. Elite Dangerous is actually DANGEROUS and those who can't handle that shouldn''t take part in either open or community goals and tbe like. But combat logging is an attitude where one wants the sweets but not diabetis.
C-loggng is an offcial exploit and punishable. I am lookng forward to the day where c-logging gets fixed.
