A lot of players are done playing PVE only and want to PvP to keep playing. This has drastically reduced the pool of peaceful lobbies. Any aggro rating above a 0 will put you into a PvP lobby now. So if you want PVE only, you don't get to shoot back or loot raiders without your next 10 games being PvP. When you go in a mob a care bear lobby, your next 20 games are PvP. In the rare occasion that someone attacked me in a PVE lobby, they wipe out everyone, I mean everyone. Not one of us shoot back. They usually find the players working together to hunt arc and kill them all in one spot. In a duo game, a team killed 10+ all in one spot, without any resistance. On the flip side when I play a PvP game, I would hate going into a lobby where nobody shot back. That is not fun at all. The people mobbing peaceful lobbies are griefers at their core and not actual PvPers.
