Easy Badass Ranks
Using a second controller create a new character and join the game as a guest. At the very beginning of the game have the two players unequip any mods and shield. Then using your main account stand directly in front of the guest character and win 50 duels (to start the duel melee with both controllers, melee again with the main controller to win). Doing this will provide a total 166 Badass Ranks. Create another new character and keep repeating this process until you have the desired amount of Badass Ranks.
