WPvP is a myth all it ever was was ganking people who were questing/leveling and feeling big about themselves. I also find it hilarious PVP players get mad that PvE players beat them in "WPvP" because they are in PvE gear and not PvP. uhh your in the world aka the ENVIRONMENT (the E in PvE) so why would they be using PvP gear when they are trying to do what their PvE gear is for.
I ignore PvP as much as possible not my thing and im terrible at it, but there have been a few times on Timeless Isle where I've flagged myself on a rare by hittting another flagged player, I usually walk away in a "oops my bad" action if they insist on continuing I will fight back win or lose (I couldnt care less) I just respawn and carry on with my business.
PvP has its place and its not in the open world and if WPvP happens it has never and will NEVER be fair so whether you are on the giving or receiving end just suck it up and move on.
