This might be me begging to be flamed. But I am sick and tired of pointless low HP ganking.
I love the concept of world PvP.
I don't mind being owned, humiliated, and spat on.
But I do mind it when whenever world PvP is on the radar, it is in the form of people ganking others that are on >30% health and fighting two or three mobs. For what? Half an Honor Point and an additional 0.1 mm to their male organs?
You can almost picture the douche not even bothering with half a smirk, because he didn't even care about the kill. It's almost like a forced behaviour of a sociopath, not doing it for his own gains or even his own amusement, but because he can make another person suffer.
I think there ought to be a system which promotes and rewards kills that really are honourable - say, you fight alone, or you begin the fight when your enemy has at least 70% of his HP. Hell, you should be rewarded for fighting when YOU are on low HP, not the other way around. That would be kicking ass, not killing people on 10%.
This meaningless ganking, however, has got to stop. Don't tell me that's what PvE servers are for, because this is not a matter of avoiding PvP. This is a matter of implementing good design to actually make PvP enjoyable and a bit demanding - thus also more rewarding.
