I would hope that this becomes somewhat less of a problem once there is more to do in the game. At this point, your choices are:
kill monsters
mine
stand around and chat
If you want to increase your stats, the only productive way of doing it is killing, as mining takes way too long and ore is worth next to nothing at this point. So you need to kill monsters, and lots of them, to get trias an PPs to advance.
And I\'m not talking just about PLers here; even to get just a few levels in your weapon of choice, and then to buy some decent equipment, takes a fair amount of killing. If you don\'t want it to take weeks, you pretty much need to stake out a spawn point and go at it.
Of course, that doesn\'t mean you have to be a jerk about it; you don\'t need to spend hours in the same spot, and if someone wants to group with you, let them in and go find some bigger monsters you can handle together.
Back to my original point: Hopefully when there are more things to do, people will find other ways to amuse themselves. If I could mine some iron, sment it into steel, and hammer the steel into a sword, then I wuldn\'t have to camp out at a spawn point for 6 hours so that I can afford to buy the sword.
Or I might not want to buy a sword in the first place. Maybe I set up an apothecary shop: I dig up herbs, I purchase other ingrdients from players and merchants, I make potions, then players come to me to buy them. At this point, this option is unavailable (like a host of others), so I do what most other players do: I kill lots and lots of monsters.
There will always be players who camp out at spawn points and act like jerks. But in the future I think the majority of those will either find something else to do in-game, or get bored altogether and move on to the next game.
