Hey there. New to this forum. I think I have an idea to prevent combat logging.
Okay, logging is cheating. I first played in Open a couple of days ago (not counting once in then past when I accidentally left in open after taking a mission from Sothis/Ceos and got killed). I was fine in Solo but I thought I'd see how it is to be in Open. I had no idea how much different combat is. I didn't know the difference the engineering would make. So I lost my Anaconda once and logged the second time. I wanted to see what I did wrong but after talking with a couple of CMDRs I understood that I had no chance. Simply because I don't devote enough time to upgrade my ship and I'm just not as hardcore a gamer as others. I won't practice as much as others. I don't care to do so cause I don't want to think seriously about anything other than my real-life worries. Then I tested my Fer-de-Lance and since I knew what I was getting into, I stayed and got blasted.
So it's like I stand no chance if I play in Open. But still I think we (simple gamers) have the right for it. We bought the same game after all.
I think that creating certain player levels outside the game (not the competent, elit, dangerous thing) can help prevent combat logging. Like 5 "leagues". We all start in No3. If my win/loss ratio in PvP is 45-55% I stay in the same league. If I win more than 55% I go to league No4 whereas when I get less than 45% I go to No2.
This way, after some cycles, I'll get to play in Open with CMDRs of the same level as me, more or less.
The different "leagues" could also effect the PowerPlay respectively, like level 3 is the base, level 4 = x1.5, level 5 = x2, level 1= x0.5, level 2 = x0.75. So if I'm a rookie and play on the safe side, my deeds won't have the same consequences with a top class player.
Still, a top class trader can be at the same level with a top class pirate, if his ship is engineered to cool down fsd faster and by having stronger shields etc, so it won't end like "traders in level1 and pirates in level5"
That's a general idea, the numbers are just examples but I think that this way, the game would be less frustrating for everyone.
Rookies have the right to play with others without being sure they'll be killed more "sooner" than later and experts can feel more sure their enemy won't log, since they won't be so easy to kill anyway...
Sorry for the lost post after all
We have something like this in the game already (albeit with NPCs), your combat rank determines the difficulty of those that go after you. Broadly speaking the playerbase takes your combat rank into account when choosing to interact, aside from the ship you're flying & where you are it's the only thing a stranger knows about your experience level, and when you get to the higher levels it's not a good indicator of PvP experience at all.
In an openworld game like ED any player could come across another, it's up to the player to decide how the interaction goes down. Your proposal would cut down on ganking but would equally cut down on the help experienced players can give to novices.
I started another thread on PvP Piracy vs Karma that covers topics similar to your idea, could be worth a read
