Playing through the game for the first time, my level 13 Mechromancer is smashing her way through a bandit camp. After clearing out the initial wave, I move forward and come face-to-face with Bad Maw and his Merry Midgets. This guy is an actual boss (splash screen and everything) and he has this massive shield which carries his midgets.
Thankfully, Deathtrap still has a few seconds left before it needs to recharge and it moves in, distracting Bad Maw and giving me enough time to chuck a DoT corrosive grenade. Less than 15 seconds after Bad Maw attacks, he and all of the Merry Midgets are dead.
