People need to stop calling everything they're not 100% comfortable with "griefing". I send out a warning first, asking people to pick a side or be treated as enemy when I see somebody loitering around at warzones, since there are some who likes to avoid picking a side just to be able to sneak up on you later while you're preoccupied. But one shouldn't be surprised if others aren't as accomodating. It is a warzone after all, you should expect to be fired upon.
