Not sure if it was around before or not. Personally I like the gamemode and wouldn't mind seeing it permanently introduced. However its the one gamemode I have found the most hackers in. Also when I'm not playing with people in a party then I can't usually pullout a win. Can't win a 1v4 against a 4 man team sadly. Other than that the squads gamemode on a duos map is really fun and fast paced and I've enjoyed playing it since it started.
