I don't know why FD don't just put in another start option alongside Open, Group & Solo. PvE, where player weapons and collisions do no damage to other players.
I'm sure it's been raised and shot down for some reason or other. However, the popularity of this group shows that it's wanted/needed and, as it stands, the lack of a PvE only option is just going to fragment the player base more. I think you'd get a hell of a lot of Solo players moving to PvE too.
