Gm's we are in a mid-grade server, but pvp is steal something of big meaning for most of the players, So my suggestion is to add something like a title managing list to the top pvp/pk list...
What i mean is, for example, when a player reaches 50 pvp his title in pvp is gone (The Frag hunter) or something like that, or maybe u could make it with more humor like (The Killing Chicken). This could start from 50 pvps and goes one after to 100 pvps next title and then to 200 pvp next title and goes on like this...
Finally to every title they could take some meaningless reward like a hat or something...
Just a seggestion always to make the community hunting the fun site of game and a more hummoristic one...
