Yeah it does seem to be intentional to get people to spend more time in backpacks and buy menus, maybe to slow the sweatlords down. Could be good when the game works properly all the time. I do feel very exposed at buy stations so I try to be quick, but then start getting shot and press the wrong button to exit and get stuck in a menu while getting shot at! Doh!
I did get three kills at a buy station recently, people kept arriving in highlighted red cars, straight after me. All solos, no squads luckily. Next time the game crashes I might camp a buy station in an angry protest!
There’s definitely people camping Exfils in DMZ, although hilariously, in my last game last night, after miraculously not crashing, then even more miraculously having a random squaddie who was good, we had a great time, completed two contracts and my lotus mission, got an LTV, made it to the Exfil; and then both got downed while inside the exfil chopper…but successfully exfilled while both downed and clearly dying. That was great.
