Um…Griefing IS PvP. It’s ALWAYS been about griefing. It’s naturally griefing.
When you’re out in the world alone, you’re scissors to somebodies rock. You think it’s any more fair if a Rogue comes and kills me out of stealth is my level or not? I’m dead, he’s not. When I rez, guess what? I’m going to be dead again if the Rogue decides too. Cuz Rogues eat Warlocks for lunch and then go and get a pint.
You want “fair”, go to Arena. In the world, it’s Griefer v Griefer.
Or do you walk up to your victims, bow, wave, and then say “En Guarde”? instead of pouncing from behind on your wings, and stunning them (or whatever it is that DHs do). But not against the Blood DKs or Paladins. You stay away from them for some reason, I’m sure.
