Well screw it, as arguments are the only thing this forum ever has seemed to grasp.
BGS effects more than just your immediate game, it's PvE right up until the point where it starts effecting other people's game, then, I'm afraid kiddos, it becomes a PvP activity.
Hence why people don't like the idea of people not being out in visible veiw doing what they do.
Let's be honest here, considering the vast number of people who are utterly phobic of social interation in an online game, do you really think you stand to be blasted out the sky every two seconds by your fellow PvEers? Because you won't. Why? Because they think like you.
And as for the threat of PvPers.. They are hugely the minority, if there is more people populating open play, the odds of you even being targeted drop SIGNIFICANTLY.
Anything that has the potential to effect anyone else's game, should be mode locked to open play. Why? Because it is NOT a one man band activity.
It's that simple.
I really wish FDev would stop worrying about what thir player base will do in spite, and just make the damn move already.
