Matriarch at Dam Battlegrounds solo queue and two raiders with Tempest IV just camping in a building killing me when I ran inside to hide from arc while saying Im friendly

Are they actually exploiting the queuing system? Who would even bring this gun to fight a Matriarch. They didn’t use proxy chat just straight up killed me.

Also few days ago I went same map but harvester just free loadout and two of my random teammates had medium shields and good weapons. They went all the way around the border of the map to meetup with another group who killed me on spot and then the 5 of them went to kill the Queen. Again none of them used voice chat at all while I was talking to them
