Guild Wars 2

as stated above.
I really want to pvp with everyone i find in open world, not only in PvP server and WvW.

/disagree 100%

I enjoy the part where you can play PvE without some players that think its funny to kill you from behind. Cant disagree more

lol..its not like we can just kill anyone, something like a permission to pvp each other. if both player agree, then we can 1v1 pvp.
