THIS.
I'm not a PvPer. I don't want to spend 4 hours on a 40 man raid only to have PvP loot drop. I'm sorry if you don't like the PvP grind, but that's how we get our gear in PvE- we grind and farm and harvest and grind and bake the bread...
That metaphor got away from me, but you know what I mean!
I just watched a dev interview where they said that the best pvp gear in game would be acquired from warplots. Further more I haven't read anything about pvp gear dropping in PvE raids, and I've been keeping tabs pretty extensively on this subject seeing as I'm a huge PvP buff.
Lastly they announced that the PvP gear you do get will have two stats unique to PvP gear. Which are PvP power and PvP defense. PvP power increases your dmg to enemy players, whereas PvP defense nerfs the amount of dmg an enemy deals to you. So kinda like how WoW has pvp power and resil, basically the same concept.
