You will never have a good pvp community unless player ownership is tied to the pvp system. Every game that has done so had/has a vibrant pvp community.
E-rivalry requires symbols of e-honor (cities, bases, space stations, houses, boats, spaceships, ect...). Until there is a major player and guild centric dynamic around pvp there will be nobody who really "cares about it". In the absence of tangible, expensive, and valued items that players can take from one-another, pvp is no more serious or "cared about" than an amateur softball league.
Knowing BW if they would bring something like that in the game you'd have to unlock a character perk for 10 mil. once you get that item. xD
I'd be happy if they'd create something like Wintergrasp at least for a start. The only thing I really miss about WoW is messing up stormwind with 3 guys.
