Pking is a very touchy subject here. Everyone AFK kills. I used to hate it, it happened to me so many times. Now I do it all the time haha.
Anyway, you'll very rarely find that you get the chance to 1vs1 someone. Many will just say that if you want to 1vs1 then use the deathmatch system. I suggest trying to find a team, your characters a beast, most teams would gladly have you hop in. Failing that, start your own.
I completely agree that there needs to be more incentives (in the form of gp/item/exp rewards), across the whole game though and not just wilderness in my opinion.
The wilderness is dead a lot and on the rare occasions you find a solo'er, they multi log or team logs in. Which is shit.
A bit of a long comment but +1 to your post.
