I Pk, and I skill.. As a competitive person, i enjoy pking much more as it actually requires skill to beat the other person. I personally do not enjoy clicking on a tree/rock for hours on end, and when i set goals for myself that include skills, i find it becomes a chore. A chore is definetly not something i want when playing a game. Granted, it is very hard to stick with a goal for many skills, as they can be long and boring. But i guess some people enjoy skilling, so whatever floats your boat :)
