Here we go. If Blizzard refuse to solve our problems, we'll have to find solutions by ourselves. Playing on PVE server? Have chosen it cuz you don't want to participate in PVP at all? Hate to constantly watch, where you're clicking, cuz crowd of PVP-flagged griefiers are trying to pull you into PVP? Blizzard refuse to do anything with it?
