Can NPC's stop "pirating" you?

[VoluptaBox]

So you haven't noticed that the more players there are on the server the less NPC's there appear to be, or that is how seem to be for me.

That is true. But if you stay in a place long enough, say to duel someone, you will eventually get swarmed by a dozen or more NPCs. Annoying as hell and for those of us with not so good connections, lags the hell out of us.
