For me, I’ve never had this issue so far. I’ve heard people complain about it though. I’ve played other extraction shooters where it is an issue though. I think part of it is I expect people to be at extract. It’s when I have the most to lose and where every player is heading eventually. It also alerts players when it’s in use. It’s a natural point of contact.

Because of this, I am cautious around them. I rarely just run up to the extract. I move toward them, but at a tangent, not direct. I’m looking out for players and for ARC alerting to players. Once I press the button I back away by at least 10-20m and stay in cover. If I see other players I’ll almost always ask if they want to leave together (while staying in cover) and they usually do. Other people at extract are usually also full of loot and have little to gain by fighting, and a lot to lose. People will usually be friendly if you ask, but hostile of you don’t because you’re an unknown and they have high risk.
