I read halfway through this thread and all I see is a bunch of people whining about how "PvE" players may get excluded from PvE content if there is open world PvP in a particular area. I don't understand how you are being excluded from anything? It's YOUR choice to exclusively PvE and no one is forcing you to participate in content that is quite possibly aligned toward players who actually enjoy both aspects, (or at least partake) in both aspects of the game. Maybe they want an area to reward people who have put time into both PvP and PvE? Is that just too simple of a concept to understand? If this area ends up like that, go take the time to get some PvP gear and hold your own in PvP, it doesn't take that long.
I am not some PvP nut either, I play both aspects of the game and would greatly appreciate an area that encompasses both PvE and PvP. If you are heavily tilted toward either side and wouldn't like something like this, then it's really easy... Don't go there! The only thing excluding you from said content would be yourself. If you want to participate.. go get the gear!
