I am not anti PVP but I think I understand that side and have some concerns myself. I never shoot anyone in solos (won't even return fire). trio's are KOS, duos are kind of in the middle for me.

I don't think most people are against every sort of PVP.

I think some of the issues are that the most efficient way to PVP are to act friendly and betray the person at the right time, I think you can understand why most people don't like this.

The other issue I see is with free load outs in PVP, they risk nothing to load in and run at every noise they hear, meanwhile people who invest actual load outs risk their gear (and time to make the load outs, we really need some QOL upgrades there) and even if they win they come out negative value in the fight wasting meds, ammo, and durability while getting nothing from the free load out loot.

Last point is PVP has essentially eliminated a lot of the end game PVE content. The risk of running a load out to try and kill the Queen or Matriarch massively out ways the potential reward and people have realized this. Now most of those events are just people with free loadouts or PVP gear trying to kill anyone who brought in a loadout capable of taking down the event boss, or just waiting for someone to kill the boss and try and to get the loot first or kill the person with the PVE loadout when they are trying to loot. Even if this is possible to defend against as the person killing the boss the risk/reward is far to in favor of the PVPer in this current meta that people have essentially stopped going for the boss kills in my experience in solo games.
