I do like the idea of a server that is fully PVP but as you have said it does have issues and it does take away from the fun of the PVP, if it was to happen I think there would have to be strict guidlines setting out when pvp is OK to happen, and also that if you lose your stuff the other pseron does not actually have to gibe stuff back etc would make things a lot more enjoyable, maybe a couple of safe zones too, (if it was to happen i would probably deadlock my tardis and hide in there forever xD.)
