I knew someone was going to ask that. I'll try and find the quote made, it was some time ago mind, but it was something along the lines of 'the majority of players are PvE', and was insinuating that as Open is a PvP environment, that most players were either in Solo or in PG's. It is a fairly well known comment.
That's fine, I recall that comment. I didn't interpret it that way, but I can see how someone might.
My view will be skewed because my 'community' is that of ALD/Powerplay, many/most of whom (that I'm aware of) even PvE in open in my experience.
