In a recent interview with Opposition Podcast, one of the Carbine developers (Jen Gordy) confirmed that there will be PvP server rule sets with open-world PvP. At the same time, she also confirmed that on a PvE server players can 'flag' themselves for open-world PvP if they so choose. Neither of these are for objectives currently, as there are no open-world PvP objectives in the game. All PvP objective play is contained in the Warplots and Battlegrounds.
But, my poll still stand at point: Which server will you play and why?
I'll be playing on an open-world PvP server, much as I'd choose when I'd originally played WoW, and on Warhammer, and on Age of Conan, and on The Old Republic. It's fun to always look over your shoulder, never knowing if there's someone lurking in the shadows waiting to kill you mid-mob fight; or to be lurking the shadows waiting for someone to just barely get to the resource node and then attack them when their guard is down as they try to gather (much to what I do currently in GW2 borderland maps :P).
