Not that old , WoTLK old, but I agree that part was rather subjecitve because I spent most time on private servers, and 95% of popular private servers are PvP, but I would bet that most population has similar history and likes it the way it is now.
Yeah, but I want to keep ability to kill enemies in situations like gathering herbs and mines, farming things, questing etc. , if they are doing same thing as me and i can kill them sparing me some time, why not? It seems natural to me, disabling big part of game just because few bad apples doesn't strike me as fair.
