The fact is, it's a niche game so you will always fight the same people. Small community = same names. This isn't always a bad thing, there's rivalries, and your name carries weight. And people won't be everywhere always, there's half the map where it's terrible spawns in terms of efficiency, nobody is going to be camping kobolds after their first week, it's just not worth the time. If you need leather, there's higher tiered mobs which are harder, but more rewarding. That's just the fact of the game, as such hotspots. High tiered mobs that pay off the best. Same thing happened in other popular mmo's, there's a valuable spawn which draws people to it, and pvp breaks out because of people contesting it.
