World pvp! reward it and people who rolled on a pvp server will have the biggest WZ they could hope for!
drop comms or something...anything... something simple will do so much
World PvP that gives rewards other then the pleasure of the PvP, is still faux PvP as far as I am concerned.
If I have to hand out chicklets to get you to do open world PvP.... something is broken.... the player base.
