I do not want to do two hour world boss kills. I do not want to have to group up to do questing in khitai. I do want to be able to help out someone fighting mobs in paikang and not have to watch my back.
So, no, I would guess that the vast majority of Crom players would not want full open world pvp. Otherwise the border kingdoms would be full of pvpers on Crom right now.
MAYBE if they made a pvp zone for all zones as an option...but then we get all the trash talking pvpers in global again. Some of who are pretty entertaining, I have to admit. But maybe Funcom could make a 'pvp global' channel.
And it doesn't need 'roaming gank squads' to be annoying. Having two to three mobs on you and getting attacked from ambush by a (fill the blank) who takes advantage of your lower health due to mob fights is a gank in my definition, whether by one player or a group.
