I can't stand people who do this, it's like playing with codes, takes no skill and ruins the game. I remember playing a squad rush match and a clan of 4 guys were on one side and me and 2 other friends came into the room with the other team already behind us doing this. What made it worse was that all 4 were medics on the attacking side. We delayed our spawn times and were able to spawn in different spots and we made them leave lol.
