Recently I've started playing on a PvP server (see my signature) and of course, I've been ganked a lot. However, I have found a way to NOT get ganked that is very easy, and common sense but many people don't think to do it.
It's really easy and has saved me lots of ganks, if you see an opposite faction by you and they either have you targeted, or are really close to you, just /wave at them!
Okay now some of you may be thinking "Okay no shit of course, but they'll still probably gank you"
Not necesarrily. It's kind of a pycological thing, 90% of the time they'll wave back and leave you alone. However I've found this really only works with lower levels, it can work with higher levels but it usually doesn't.
The /wave gestures that you're either a nice person who's not worth killing or that you wouldn't kill them or attack them. This is kind of a dumb post but whatever, I'm bored, tired, and sick. I hope you guys can actually use this and hope it saves you hours of walking back from the GY.
