And yet there are many that do not agree with your perspective. Basically, the short version is your standpoint is tantamount to being a griefer/ganker apologist.
Any C&P system will not deal with the more excessive PvP behaviours without a supplemental support system like the proposed karma system, and since ED is NOT intended to be a PvP combat focused game a karma system would be completely in-line with maintaining the original design intent.
No doubt there will be some exclusions to the PvP behaviours such as when two players are on opposite sides of the battle in a CZ but the exceptions are mostly always going to be reserved for situations where the target CMDR has opted into the combat activity (and no - simply playing in Open does not count).
Did I say my opinion was anything more than my opinion? I don't like griefers who kill without reason. I do like proper pirates, someone who makes a demand. Even proper pirates find themselves killing from time to time. That should be the line between karma and c&p. There might not be a perfect solution but I think the distinction should be maintained. I don't like hate speech but I still believe in free speech. They are not wonderfully conducive viewpoints but they exist all the same.
Your view is that ED is not a pvp game. That is your view. It is not suggested or supported by game mechanics which leave the choice to the player (open, private, solo). Stating otherwise is completely contrary to all observable fact. For the love of god, power play encourages killing for no other reason than someone is "hostile". Any claim that pvp isn't intended is just blind denial of fact. Can you not buy hatch breaker limpets? Can you not turn crime reporting off to duel? CQC isn't a part of ED? We have guns right? In the history of gaming has there ever been a game where players who weren't on a team were placed in an area together with weapons and weren't expected to shoot each other? Please name this game. That's just wishful thinking. ED is not 1984 Elite.
But that's not the plan. Of course pirating and killing will be handled by the C&P mechanic, as they are now although I do agree with you that it urgently needs fixing. Each individual crime attracts consequences appropriate for that crime.
The only place a karma system would come into play is to permit the game to respond to patterns of behavior, not individual actions. While this may affect how harshly a C&P system responds, it's never going to make C&P respond without you committing a crime to trigger it, or stop C&P responding if you do. And if FD see fit for behaviors outside the C&P remit, such as CL-ing, to be part of ones karma then that's fine too.
Even if your karma is in the toilet so badly that every NPC, station and faction in the game is saying "If he puts a single foot wrong, I'll have him!" you'll still have to put that foot wrong to bring the world crashing down on your head. Karma will only moderate how the game behaves towards you, it wont (or at least shouldn't) carry any specific immediate "punishment" like explicitly committing a crime and triggering the C&P mechanics do.
I think pirating and being an outlaw should be an occupation, like mining and trading. They should have different ranks since the PF frowns on it. Someone mentioned needing to buy fake ship ID's to land in non-anarchy systems. Black markets not readily available everywhere. Hatch breaker limpets not available everywhere. Murder should mean major faction wide wanted status and a real clock. 7 days for each kill, no reset on death. Or maybe each murder should increase the wanted status in LY from location, doubling each kill. There are options that still create interesting game play without excluding such play. I do think it has a place in the ED universe. Without the chance to be killed by a player, why play in open at all? Mobius is a fine option!
My opinion is that the punishments for horrible Karma should be more severe and less RP oriented than just committing crime. Maybe people with bad Karma shouldn't be allowed to wing together, should be less likely to get instanced together (so they don't show up in hordes just to troll founders world for a night (or month) ((or eternity))). Maybe the game could check for things like a cargo rack, cargo scanner and hatch breaker limpet before deciding murder is bad karma or just crime? There are options and they should be considered.
But that's just my feeling. I happen to like the danger open presents and don't want to see it go away. There are other ways to play for people who dislike that.
