Jade Dynasty is turning on their PvP only server, "The Wildlands." On this server, all of the PvE only zones have been transformed into PvP zones, meaning that you're a target the second your character hits level 30. Using your Esper's botting function on this server is much more dangerous now, as going on auto-pilot means that you'll be defenseless to anyone who crosses your path.
Still, for those who prefer a much more hostile environment in their games, The Wildlands server looks to be exactly what you're looking for. Now, join battle and destroy!
