I'm not a fan of having to run back to Sanctuary or Liar's Berg to constantly change my skills over and over. Are there any other Quick Change stations kicking around that I can hit, to save some time?
Captain Scarlett and her Pirate's Booty:
Mr Torgue and the Campaign of Carnage:
Sir Hammerlock's Big Game Hunt:
Note that there is a Quick-Change station located just before any DLC's 'invincible' boss.
There are only two, one in Sanctuary and one in Liar's Berg.
