Would very much support this.

Looking at stuff like the different region population or overall interest in PVP there would be a bunch of problems probably. Assuming they'd go for one PVP server for each region (NA, EU, JP) I'd be unsure if atleast the EU server would provide a large enough player base to have a healthy economy and such.

Now let's say the player base is large enough etc they need to figure out what kind of OWPVP they want to implement:

*Ganking is fun, on the other side there needs to be a lowbie protection. Assuming you'd flag yourself so you can kill anyone - and be attacked by anyone(being able to attack anyone just like that without being flagged will probably not happen) - you can add a certain amount of points for every lowbie killed, those points disappear after a certain amount of time and until those points are gone you stay flagged.

*FC vs FC would be cool, give some rewards for a certain amount of wins like mounts/pets/vanity/whatever else that keeps people doing FC vs FC. I'm sure an exclusive housing area or an exclusive plot in the Mist etc for lets say the top three FCs would be motivation enough. That would need a ranking system though, maybe monthly based or something. Problem with that is feeding kills and such, that would need to be prevented somehow before the system goes live. Also, safezone hugging needs to be taken care of: assuming player A from FC Y kills player B from FC Z FC Y would just stay in town til the FC vs FC timer is over so they'd win with one kill. (Also kinda stolen from Tera)

*Overall tracking kills/activity, create a ranking, give the top ranked players exclusive titles/mounts/minions and such. Again, stuff like that has to be monitored so feeding doesn't happen. (probably stolen from Aion, dunno)
