Just a thought if the menu glitch can still work somehow. Go into arena with 2 controllers and use controller 2 and create a class. Hover over the perk you want and then join a friend whos in a public lobby and whilst joining use Spotify to freeze the game and it should then have the perk choice in the background, go into create a class with controller 1 and go onto whatever perk number you chose and accept with controller 2. Could this work maybe???
