I'm not trying to bang on anyone that want's to use any skill, I was just giving my humble opinion. I am a bit of a scavenger and I pick up, and sell everything. This is easy with the ability to warp back and forth from the BF's to sell it all off. I have more gold then I know what to do with, so for me, PP isn't needed. I invest all my points into my weapon of choice and am a killing machine because of it. As I said, that works for me, and whatever path you take, have fun with it.
