You'd assume it only "takes less time", however that's just an illusion. Sure, the initital Repping might be easier, but you'd have to fix your rep much more often then you would with the current system, so if you think about it, this system makes repping take much longer.
It would be something of a bummer if a few of your mines accidentally collided with a bunch of low level friendly npcs and upon return from the fight you would find yourself hated by, for example, all of the liberty lawfuls until you find a bunch of criminal npcs to fix things again.
I'd be very much against killing npcs affecting your rep more.
Slightly more interesting is the following scenario.
You're on a KNF tagged and ID'd ship, and a Samura ship is going mental, killing stuff left and right, and the way of dealing with this, is to shoot the guy.
You shoot him down and kill him, then suddenly all the Samura NPCs are hostile.
While in essence I agree with Coin, that IRL it should work that way....
Lets say you're in a furrball and you drop a nukemine which misses your target, and some idjit allied NPC flies right into it.
Now this happens to me ALL the time, i don' tknow about the rest of ya.
But I sure wouldnt want tohave to fix that everytime it happened, I'd just quit fighting altogether.
Especially considering the fragility of keepin Junker reps neutral.
Potential issue for neutral traders/smugglers who somehow manage to successfully defend themselves against a pirate. And then the whole pirate faction goes mental on you. Neutral repping benefits from smaller rep changes.
Plus this invites trolling by attacking people with an overly weak ship just to mess with reputations.
Wide awake in a world that sleeps, enduring thoughts, enduring scenes. The knowledge of what is yet to come.
From a time when all seems lost, from a dead man to a world, without restraint, unafraid and free.
