Its P2P above the P2P fence. The reason PKers prefer F2P is that P2P is too overpowered and 3hit heavy. For low levels P2P pking is tankmages only which takes the fun out of PKing. Other builds are way outpowered.
Ill try to describe what it looks like when wild(castle) is P2P. Most of the time its completely empty. And when its not you can see a team of 4-6 unique players on tankmages. Usually what happens is 2 decent PKers log in and beat the team with ease while multiclienting against the bigger team. Even though having the numbers the team will scream "omg multi", run, log and its back to dead again. Even though these players have other chars they could use for PKing they chose not to use them because it is not safe enough. Some even keep making posts about PKing on forums as if they would ever PK on any other char than level 30s 40s.
Theres some hybrid PKing action as well but other than that its pretty dead when its P2P. Occasional flats clashing but as always one side will feel the fight is unfair(or they would prefer to gather the benefits from fort uninterrupted by stupid pkers) and the fighting stops soon after.
Someone please tell me Im wrong and thats not how P2P pking looks like.

Good call numb nuts, now the wilds more dead than ever. This is why the pkers shouldn't have an opinion. It's a skillers wild, the pkers are followers and always have been. They log in for 30 mins a day and if there isn't any pk it's more like 5 mins. Let the great ideas come from the people who play the game for hours.
