That may be true, but there are always peasants. I'm not complaining about one particular dude, who gets beaten every time. That would be talking about Obscurio, and I find it funny to kill him over and over again.
I'm talking about the general phenomenon of actively and deliberately searching for peasants to kill. Finding obviously much weaker players, and killing as many of them as possible shouldn't be the main objective, as far as rewards go.
The only way this could be fair is if:
-You would gain as much points as the level of those slain: you gain 2 for a level 2 peasant, and gain, I dunno, 40 for Finn.
-Horses would count for kills.
If you would gain more points for taking out REAL threats, than this would be splendid. But that just seems impossible to implement.
