I enjoy PvE, but understand there is want for PvP. If you want to make me deal with PvP all the time then give me some immersive suspension of disbelief. Make ‘murder’ actually a deterrent instead of a trivial penality. Flag offenders for hours even after respawn. Make bounties for ‘murder’ incremental and exorbitant, including gold and XP for tracking down a ‘murder’. Or make that penality actually have consequences, like permently loosing / dropping firearms, funds, items, and or Perminant loss of mounts. Make towns and cities raise the calls for marshals and mobs to hunt down offenders.
If you want to kill other players there are events for that. If you really have to pull the trigger on a PvEer, have a consequence that is meaningful. Otherwise, speaking personally, I have no reason to buy gold (mocotransactions coming soon) to lessen the grind or continue to play in lobby after lobby of griefers.
